Last Exception errors despite no mods/cc (PC)

Please help. My game keeps generating Last Exception errors nearly every time I play despite using no mods/cc. I uploaded a link to some of these recent files here: https://drive.google.com/drive/folders/1fGsWtiatLbm5JZok2-vv-J3IzZ1Yj4yt?usp=drive_link

The Last Exceptions errors affect multiple different save files and it's been going on for quite a while. I'm very worried it's corruption and my saves might become unplayable. :( Uninstalling and reinstalling the game did not help.
