I think you've placed the game in a folder that requires administrator privileges to write to. Please try moving the game folder to your desktop.
I'm hoping this is what you're looking for, this is for the manual save fail
and this one below is the autosave failure
I'm not sure if there's too much of a difference but I'll send both anyways, also let me know if any of that somehow leaks any personal info or whatever I'm definitely overthinking but just want to make sure
