Savegame got wiped

My Save Game got wiped.

I started the game yesterday for the first time in a few months. It only shows me “New Game”. I cant load my save game.

I tried using the .bac but it is the same.

I have over 500 hours in this game and unlocked every collectable, gear, weapon …
If I cant get my save game back i’m done with this game and publisher.
