After years of working perfectly fine, this game decided to stop me from playing it.

Now any time I press a key on "press any key" screen the game loads up into main menu, only to immediately jump to a loading screen that crashes the game. Crash logs are empty, game doesn't allow itself to be properly tracked in event viewing. I did just about anything from updating drivers and disabling the overlays to a full clean reinstallation including Steam and Ubisoft Connect. Has anyone faced this before? Has anyone ever found a solution? Support has been entirely useless.
