Tom Clancy's Rainbow Six Siege

"Initialization Error 2" Popup
I've been having this error for a while now. I try to launch the game and a small window pops up saying "Initialization error 2". I've tries running the game as administrator, in compatibility mode, deleting and reinstalling both the game and Ubisoft Connect, verifying integrity of game files, adding a firewall exception, updating my drivers, nearly every possible fix I could think of. Anyone else having this issue/know any fixes??
