Microsoft says it’s working with Ubisoft to fix a problem with its latest Windows 11 update that’s been crashing some games, and it’s put the update’s release on pause for devices with those games in the meantime.

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.

According to a message on the Microsoft support page, users who have installed Windows 11 version 24H2 "might encounter issues with some Ubisoft games". The affected titles are Assassin's Creed Valhalla, Assassin's Creed Origins, Assassin's Creed Odyssey, Avatar: Frontiers of Pandora, and, most notably, Star Wars Outlaws.
