Windows 11 users are experiencing system instabilities, including game freezes, crashes, and blue screen errors, following the KB5121003 update. The issue is linked to RGB software that conflicts with essential system components. Affected online multiplayer games, such as Arc Raiders and Marvel Tokon: Fighting Souls, are particularly impacted, with players encountering "EXCEPTIONACCESSVIOLATION" errors. The problematic driver, often named "inpoutx64," is associated with RGB lighting control and operates in kernel space, leading to vulnerabilities that anti-cheat mechanisms aim to mitigate. When the driver is blocked, it causes critical errors resulting in system crashes. Microsoft has suggested temporary workarounds using compatible programs like SignalRGB or OpenRGB to manage RGB devices without triggering anti-cheat alerts. Users are encouraged to report issues through the Feedback Hub for resolution prioritization.
