Microsoft confirmed that the latest update for its Windows 11 operating system may cause “certain games to become unresponsive”. The update released on August 11, 2026 — KB KB5121003 — for Windows 11 version 25H2 and 24H2 may cause several issues when playing games, writes Microsoft in the bug report.
According to the description, players may experience the following issues among others:
- the game application becomes unresponsive
- the game application closes without notice
- the error “EXCEPTION_ACCESS_VIOLATION” is displayed
- the device restarting without warning
Affected games include ARC Raiders, Marvel Tokon: Fighting Souls and The Finals. Other gamers may be affected as well, but Microsoft says the issue has been reported for a “limited number of games” only.
Microsoft has not published a workaround at the time, which leaves gamers with just two options:
- Roll-back the update to pre-August 11th-levels.
- Skip problematic games until the issue is fixed.
While the first option allows affected gamers to play the games once again without the reported problems, uninstalling the August update removes security patches and leaves the system open for potential attacks that exploit them.
The issue is currently under investigation. Microsoft says that it will update the bug listing once it has found a solution for the issue.
