@76345a  Lots of people have had OneDrive issues of some kind, and usually the easiest intervention is to disable it entirely.  If you don't want to do that, you can instead tell it to stop syncing the contents of Documents:

Please also let me know whether your system's Documents directory is pointing to OneDrive.  Open a File Explorer window, right-click on Documents in the left panel, select Properties > Location, and you'll see a file path that does or does not include OneDrive.
