GoKawiilWindows 11's KB5124010 update crashes Battlefield 6 and Wardogs
Microsoft's KB5124010 update, pushed to Windows 11's stable channel this week after appearing in the Release Preview channel, is causing crashes in games protected by the Javelin anti-cheat system, including Battlefield 6 and Wardogs. Players report the games crash within seconds of launch with little or no error information, though Wardogs users see a WD-L020 error code. Uninstalling the update has been the only workaround confirmed by affected players and, for Wardogs, by a Team17 representative.
GoKawiil's interpretation of the reporting above, not reported fact.
The update was reportedly meant to improve stability, so its apparent conflict with Javelin-protected titles suggests Microsoft may not have adequately tested it against common anti-cheat systems before wide release. This follows a similar incident last month involving the August Patch Tuesday update, which could raise concerns among gamers and developers about the reliability of Microsoft's testing process for updates that touch system-level components anti-cheat software depends on.
