How To Troubleshoot Logitech G Hub Infinite Loading Screen?

You open Logitech G Hub and all you see is a spinning logo that never stops. The app refuses to load. Your mouse, keyboard, or headset settings are locked behind a screen that goes nowhere. This is one of the most frustrating software bugs PC gamers face, and it has persisted for years.

The Logitech G Hub infinite loading screen affects thousands of users on Windows 10, Windows 11, and macOS. The problem often appears after a software update, a system restart, or seemingly out of nowhere. Your peripherals still work at a basic level, but you lose access to all your custom profiles, macros, lighting effects, and DPI settings.

This guide covers every fix from the simplest to the most advanced so you can get back to your settings fast. Each method has been tested and confirmed by real users across forums, Reddit, and official Logitech support pages.

In a Nutshell

• Kill all G Hub background processes in Task Manager (LGHUB Agent, LGHUB Updater, and LGHUB) and restart the app. This is the fastest fix and works for many users instantly.
• Run G Hub as an administrator by right clicking the app and selecting “Run as administrator.” Permission issues often prevent the app from loading properly.
• Use the Modify/Reinstall option in Windows Add or Remove Programs instead of a full uninstall. This keeps your settings intact and repairs the installation at the same time.
• Perform a complete clean install by removing all G Hub folders from Program Files, ProgramData, and AppData, deleting the registry key, rebooting, and reinstalling from the official website. This is the most reliable long term fix.
• Disable automatic updates inside G Hub settings and stop the LGHUB Updater Service in Windows Services. Faulty auto updates are one of the biggest causes of the infinite loading bug.
• Check for corrupted configuration files in the AppData/Local/LGHUB folder. A single broken JSON file in the scripts directory can prevent the entire app from loading.

What Causes the Logitech G Hub Infinite Loading Screen

The infinite loading screen happens because G Hub fails to complete its startup process. Several things can cause this failure. The most common reason is the LGHUB Updater Service getting stuck in the background. This service runs every time your computer starts, and if it encounters an error, the main app cannot load.

Corrupted configuration files are another frequent cause. G Hub stores your profiles, macros, and settings in JSON files inside your AppData folder. If one of these files becomes corrupted during an update or unexpected shutdown, the app gets stuck trying to read it.

Software conflicts also play a role. Programs like SignalRGB and other peripheral management tools can interfere with G Hub processes. Antivirus software sometimes blocks G Hub components from running properly. Windows updates can also break compatibility with the installed version of G Hub.

Finally, permission issues prevent G Hub from accessing the files and services it needs. If the app does not have administrator privileges, it may fail silently during startup and display the spinning logo forever.

End All G Hub Processes in Task Manager

This is the quickest fix and should be your first step. G Hub runs multiple background processes, and if any of them freeze, the app cannot start properly.

Press Ctrl + Shift + Esc to open Task Manager. Look through the list of processes for anything with “LGHUB” or “Logitech” in the name. You will typically find LGHUB Agent, LGHUB, and LGHUB Updater running in the background.

Right click each process and select End Task. Start with LGHUB Agent, then end all LGHUB instances. Some users report that leaving LGHUB Updater running helps, while others find that ending everything works better. Try ending all of them first.

After you close every G Hub process, relaunch the app from your Start Menu or desktop shortcut. In many cases, this simple restart clears the stuck state and G Hub opens normally. If the problem returns after every reboot, you will need a more permanent fix from the sections below.

Restart the LGHUB Updater Service

The LGHUB Updater Service is a Windows service that runs in the background. It checks for updates and helps the main app start. If this service crashes or stops, G Hub gets stuck on the loading screen.

Open Task Manager and click the Services tab. Scroll down until you find LGHUBUpdaterService. Right click it and select Restart. Wait about 10 to 15 seconds for the status to show “Running” again.

Now try opening G Hub. If the service was the problem, the app should load without issues. You can also access this service through the Windows Services app. Type services.msc in the Windows search bar and press Enter. Find LGHUB Updater Service, right click it, and select Restart.

If the service repeatedly fails, consider setting its Startup type to Automatic in the Properties window. This ensures the service starts fresh every time your computer boots up. A consistently running updater service is critical for G Hub to function.

Run G Hub as an Administrator

Permission problems are a hidden cause of the loading screen bug. G Hub needs access to system files, services, and hardware drivers. Without proper permissions, it fails silently.

Close G Hub completely using Task Manager as described above. Then open the Windows Start Menu and find Logitech G Hub in your app list. Right click it and select More > Run as administrator. Click Yes on the permission prompt.

If this fixes the problem, you should set G Hub to always run with elevated permissions. Open File Explorer and go to C:\Program Files\LGHUB. Find the file called lghub.exe, right click it, and select Properties.

Click the Compatibility tab. Check the box next to Run this program as an administrator and click OK. Repeat this for lghub_agent.exe and lghub_updater.exe in the same folder. This ensures every component of G Hub runs with the permissions it needs from now on.

Use the Modify/Reinstall Option

This method repairs G Hub without losing your custom settings. It has one of the highest success rates according to community reports spanning several years.

Open Windows Settings and go to Apps > Installed Apps (Windows 11) or Apps > Apps & Features (Windows 10). Find Logitech G Hub in the list. Click the three dots next to it and select Modify instead of Uninstall.

A dialog box will appear with a Reinstall G Hub option. Select it and click Reinstall. Check the box for Transfer my current settings to keep your profiles and macros. The reinstall process takes a few minutes.

After the reinstall completes, G Hub may show a critical error message on the first launch. Do not panic. Close the app and reopen it. Most users report that it works perfectly on the second launch. This method fixes corrupted installation files while keeping your data safe.

You can also access this option by typing appwiz.cpl in the Windows search bar. Find Logitech G Hub in the list, select it, and click the Change button at the top.

Perform a Full Clean Install on Windows

If nothing else works, a clean install removes every trace of G Hub and gives you a fresh start. You will lose your custom settings, but this method has the highest overall success rate.

First, uninstall G Hub through Windows Settings. Make sure to uncheck “Save my current settings” during the uninstall process. Next, open Task Manager and end any remaining G Hub processes.

Now delete all leftover folders. Open File Explorer and remove these directories if they exist:

C:\Program Files\LGHUB
C:\ProgramData\LGHUB
C:\Users\YourUsername\AppData\Local\LGHUB
C:\Users\YourUsername\AppData\Roaming\LGHUB

You may need to enable hidden files in File Explorer to see the AppData folder. On Windows 11, go to View > Show > Hidden items. On Windows 10, go to View > Options > Change folder and search options, then select Show hidden files.

After deleting all folders, open the Registry Editor by typing regedit in the search bar. Go to HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows > CurrentVersion > Uninstall. Find and delete the key named {521c89be-637f-4274-a840-baaf7460c2b2}. Reboot your PC, then download and install G Hub from the official Logitech website.

Perform a Full Clean Install on macOS

Mac users experience the same infinite loading bug. The clean install process on macOS is slightly different but equally effective.

First, right click the G Hub icon in your menu bar and select Quit G Hub. Open Activity Monitor from Applications > Utilities. Search for “G HUB” and force quit every related process you find.

Open Terminal and type sudo pkill -f lghub to kill any remaining processes. Enter your password when asked. Now delete these files and folders using Finder:

Go to Applications and delete the Logitech G Hub app. Go to /Library/LaunchAgents and delete com.logi.ghub.plist. Go to /Library/LaunchDaemons and delete com.logi.ghub.updater.plist. Go to /Users/Shared and delete the LGHUB folder.

Restart your Mac. Do not skip this step. After the restart, download the latest G Hub installer from the Logitech website and install it fresh. The app should open without the infinite loading screen.

Disable Automatic Updates

Automatic updates are one of the primary causes of the infinite loading bug. A failed update can corrupt G Hub’s files and prevent it from starting. Disabling auto updates stops this cycle.

Once G Hub is working, click the hamburger menu at the top left corner (do not select a device first). Click Settings. Find the checkbox next to Enable Automatic Updates and uncheck it.

This alone may not be enough because the LGHUB Updater Service still runs in the background. To fully disable it, type services.msc in the Windows search bar. Find LGHUB Updater Service, right click it, and select Properties.

Change the Startup type dropdown to Disabled. Click the Stop button to halt the service immediately. Click OK. This prevents the update service from running at all, which eliminates one of the most common causes of the loading screen bug.

Keep in mind that you will need to manually update G Hub in the future. Download the latest installer from the official Logitech website when you want to update.

Check for Corrupted Configuration Files

A corrupted JSON file inside G Hub’s data folder can lock the entire application. This fix is targeted and does not require a full reinstall.

Open File Explorer and type %localappdata%\LGHUB in the address bar. Press Enter. Look for a folder called scripts. Open it and check each subfolder inside.

You should find files named config.json and script.lua in these subfolders. Open any config.json file with Notepad. If the file contains empty characters, NULL values, or random symbols, it is corrupted.

Delete the corrupted config.json file or the entire parent folder. Close G Hub through Task Manager if it is running, then relaunch it. Many users have fixed their loading issue instantly with this method without losing any other settings or macros.

If you are unsure which file is corrupted, you can rename the entire scripts folder to something like “scripts_backup” instead of deleting it. This lets G Hub create a fresh scripts folder on startup while keeping your old data available if needed.

Run G Hub Components Manually

Sometimes the individual G Hub components fail to start in the correct order. Running them manually can fix this.

Open Task Manager and make sure no G Hub processes are running. End them all if any are active. Then open File Explorer and go to C:\Program Files\LGHUB.

Find lghub_agent.exe, right click it, and select Run as administrator. Next, find lghub_updater.exe and run it as administrator. Finally, find lghub.exe and run it as administrator.

This manual launch sequence ensures each component starts in the right order with proper permissions. Several users on Reddit confirmed this method works every time even when the regular shortcut fails.

The downside is that you may need to repeat this process after every reboot. To avoid that, combine this fix with the administrator compatibility settings described earlier in this post. Setting all three executables to always run as administrator through their Properties > Compatibility tabs saves you from repeating the manual launch.

Update Windows and Device Drivers

Outdated drivers and Windows updates can cause compatibility issues with G Hub. Keeping everything current often resolves persistent loading problems.

Open Windows Settings and go to Windows Update. Click Check for updates and install anything available. On Windows 11, also click Advanced options and then Optional updates. Look for driver updates in this section and install them.

Next, open Device Manager by typing “device manager” in the search bar. Expand categories like Cameras, Human Interface Devices, and Sound, video and game controllers. Right click any Logitech device and select Update driver.

Select Search automatically for drivers. Windows will check for newer versions. After installing updates, restart your PC before opening G Hub again. Outdated USB drivers in particular can prevent G Hub from detecting your devices, which sometimes triggers the infinite loading state.

Disconnect and Reconnect Logitech Devices

Sometimes a connected Logitech device causes a conflict during G Hub startup. Disconnecting your devices forces G Hub to launch without trying to communicate with hardware.

Unplug all Logitech peripherals from your computer. This includes mice, keyboards, headsets, webcams, and wireless receivers. Then close all G Hub processes through Task Manager.

Launch G Hub with no Logitech devices connected. Wait for the app to fully load and display the main interface. Once it is open and stable, plug your devices back in one at a time. Give G Hub a few seconds between each device to detect and configure it.

Some users found that their specific device was causing the conflict. One user discovered that turning their mouse off and on during G Hub startup broke the loading loop. Another found that connecting both a wireless mouse and its receiver via USB simultaneously resolved the issue.

If a particular device consistently causes the loading screen, check for firmware updates for that device through G Hub once the app is working.

Try Installing an Older Version of G Hub

If the latest version of G Hub keeps getting stuck, an older version may work better on your system. Some users have found that specific updates introduced the loading bug for their hardware configuration.

Uninstall the current version of G Hub and perform a clean install as described earlier in this guide. Instead of downloading the newest installer, look for version 2023.1 or an earlier release on the Logitech website.

Install the older version and immediately go to Settings to disable automatic updates. This prevents the problematic newer version from reinstalling itself. You can then manually trigger an update from inside the app if you want to try a specific newer version.

Some users have had success contacting Logitech support directly and requesting a link to an older installer. The support team has provided working older versions to customers who reported the infinite loading issue.

Keep in mind that older versions may lack features or bug fixes present in newer releases. Use this as a temporary solution while waiting for Logitech to fix the loading bug in a future update.

Check for Conflicting Software

Other software on your computer can interfere with G Hub’s background processes. Identifying and resolving these conflicts can permanently fix the loading issue.

SignalRGB is one of the most commonly reported conflicts. This RGB lighting control app can block G Hub from communicating with your Logitech devices. If you have SignalRGB installed, try closing it completely before opening G Hub.

Antivirus and firewall software can also block G Hub components. Check your security software’s activity log for any blocked actions related to LGHUB files. Add the entire C:\Program Files\LGHUB folder to your antivirus exclusion list.

Other peripheral management tools like Corsair iCUE, Razer Synapse, or SteelSeries GG may also create conflicts. Try closing these apps through Task Manager before launching G Hub to see if the problem resolves.

If you identify a conflict, you have two options. You can configure both programs to coexist by adjusting their settings. Or you can choose to use only one peripheral management tool and uninstall the other. Many users report that removing conflicting software permanently fixes the G Hub loading issue.
