[2022] Save file issue

Hi, i am having a problem where it comes up in game saying my save file is corrupt and can no longer be saved, please restart the game to fix this issue, upon restarting it does not fix the issue and comes up approximately every 5 minutes in game. I have tried deleting the game saves, validating game files and starting a new game but the error persists. the only way i can get past the error is to completely wipe my pc from anything relating to ubisoft and valhalla and starting anew. However, after doing this the game crashed and upon startup it had the exact same issue. I have now had to wipe my pc of this game and re-download 5 times now. The game is near unplayable with this error coming up as well as there seems to be an issue with when it is trying to save, the keyboard becomes unresponsive in game....
this is very frustrating as i would just like to play the game and have had to restart multiple times now and the game is basically unplayable. Please help ASAP.
