Trouble with autosaving

I'm having issues with the message "an error occured whilst saving, press cancel to return to the title screen" in my PC playthrough. I'm not sure how to fix this. I've tried running as admin, reinstalling, making sure save file isnt on read only. Nothing worked yet. Was told to try change the app permissions for it but I havent found a helpful guide as to how to actually do that. Any help would be massively appreciated as I really want to manage to play my first full run of this game. Any help would be massively appreciated, thank you!
