The Windows 11 gaming disruption is causing crashes, launch failures, freezes, and restarts on affected PCs, and Microsoft is investigating the problem. The issue affects Windows 11 24H2 and 25H2 systems after KB5121003 and later updates. Early findings point to RGB lighting devices whose drivers or components may trigger the breakage when certain games start. Embark Studios has shared a temporary inpoutx64.sys workaround while Microsoft works on an official fix.
