@layniiiiii Please post a screenshot of the contents of the saves folder, as in, I'd like to see the file names and sizes.
I would also suggest moving your computer's Documents directory out of OneDrive entirely. If OneDrive truly isn't running, use this method to move Documents:

I will say it's odd that your Documents directory is in OneDrive even though it's not running on this computer. Was it running at one point, and did you uninstall or unlink it without first telling it not to sync your data? I ask because you're not the first person I've seen who is sure they haven't allowed OneDrive to sync their files but who nonetheless report the same location for Documents.
