Microsoft has discovered that certain Ubisoft games are crashing after users install the Windows 11 24H2 update. Affected games include well-known titles like Assassin’s Creed, Star Wars Outlaws, and Avatar: Frontiers of Pandora.

Microsoft is blocking updates to Windows 11 version 24H2 on PCs where select Ubisoft games are installed due to a compatibility issue.

First reported by Bleeping Computer, Microsoft is now preventing Windows 11's 24H2 update from being sent out to machines that have a selection of recent Ubisoft games installed on them. A number of users have reported persistent, unworkable crashing, sometimes on startup, when trying to play the affected games.
