While on the Ubisoft front, apparently Assassin's Creed Origins on Steam will not run on the new Microsoft update (version 24H2). According to IGN, many people are experiencing crashes, freezes, etc.
Ubisoft’s PC woes have continued into 2025, with the generally much-loved Assassin’s Creed Origins suffering a review-bomb campaign on Steam after a Windows PC update rendered it unplayable for some.

Edit: I can confirm that, at least for me, the game now doesn't run. Man, 2025 off to a swell start already
