Assassin's Creed Valhalla bug ?????

[wardaddy]

I saved my game with gamesavemanager on the game Assassin's Creed Valhalla and when I try to open it I realize that it is a "library" file instead of "acv auto save" and that the game does not recognize.
Your software is not compatible with this game and has distorted my save ??? have any feedback on it please?
I played 60 hours on it, please help me

save :
library_0x1d1e4247

I specify that I have searched in the right folder (13504)
