Windows 11's August update is crashing games: Microsoft explains why

PCWorld reports that Microsoft's Windows 11 August update KB5121003 is causing games like ARC Raiders, THE FINALS, and MARVEL Tōkon to crash with EXCEPTION_ACCESS_VIOLATION errors. The crashes appear linked to the inpoutx64 driver, commonly used by RGB lighting hardware, which conflicts with the update. Microsoft is investigating the issue, but users can temporarily disable the inpoutx64 driver via the Windows Registry, though this may affect RGB hardware functionality. Microsoft released update KB5121003 on Patch Day in August . But KB5121003 is causing quite a stir: the patch causes Windows 11 to crash in the middle of games . The issue is reportedly triggered by a driver for RGB lighting functions, and Microsoft has now confirmed this. In recent days, an increasing number of gamers have reported that Windows 11 has been causing problems since the installation of KB5121003. Games would stop responding, error messages would appear, and Windows would crash completely.
