Windows 10: Microsoft Shares Workaround for EXCEPTION_ACCESS_VIOLATION Game Crashes Tied to RGB Drivers

Microsoft has published a workaround for game crashes on Windows 11 that started after the KB5121003 update. The company has traced the problem to RGB lighting drivers.

The issue can cause games to freeze, restart the PC, or show an EXCEPTION_ACCESS_VIOLATION error. According to Microsoft, the crashes are linked to peripherals or internal components with RGB lighting that install drivers named like inpoutx64.

There is no permanent fix yet, but the registry workaround may help until one is available. Games reported to be affected include ARC Raiders, MARVEL T?kon: Fighting Souls, and THE FINALS.

Microsoft's RGB Driver Finding and Registry Workaround


Microsoft's acknowledgment in Windows Release Health reads: "Following the release of Windows updates on August 11, 2026 (KB5121003) and later, Microsoft received reports of issues involving inability to run certain games as expected."

The company continued: "Ongoing investigation indicates that this issue is related to peripherals or internal device components which have RGB lighting features.

Such devices may install drivers or code components with file names similar to inpoutx64. In systems where these drivers are found, the issue is then triggered by launching certain games."

Reported symptoms are games freezing, closing unexpectedly, showing the EXCEPTION_ACCESS_VIOLATION error, or the device restarting without warning.

Microsoft's workaround disables the affected driver using the Windows registry. Since editing the registry can cause problems, make sure to back it up before making any changes:

1. Open the Windows registry by opening the Start menu, typing "regedit," and selecting Registry Editor from the results.
2. Navigate to the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\inpoutx64, either using the folders on the left or typing the path into the addBe sure to back up the registry before you continue, so you can undo the change if needed.ge needs to be undone.
3. On the right side, find the value named Start, double-click it, and enter the number 4 under Value data.
4. Close the window and restart the computer.

RGB Feature Tradeoff and Fix Status


Microsoft warns that disabling this registry key may cause problems with RGB features on your devices or with the software that controls them.

Users who experience such issues and want to restore the functionality can re-enable the driver by restoring the registry key to its previous value, following Microsoft's guidance on backing up and restoring the registry in Windows.

The workaround is available for users affected by the crashes, but Microsoft has not released a permanent fix. Users can apply the registry change for now and check Windows Release Health for updates.

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?
