Can't sign into OneDrive after switching PC to local account

Hi everyone!

I've been having some intermittent issues with OneDrive syncing just sort of crashing on me perdiocally throughout the day (and also refusing to save any selective sync settings that I set). One of the solutions I read about was unlinking and then relinking your MS account to the OneDrive app. But, with Windows 10 it appears that you can't unlink your account if you're signing into the PC with your MS account. So, I switched over to a local account, and now OneDrive won't login at all, and it won't let me setup a different account or anything else (unlink account button is grayed out, as is the icon because it's not signed in).

Any thoughts on how to really reset this? I've tried running OneDriveSetup from the AppData folder which did nothing. I've tried running the onedrive.exe with the /reset argument, which did nothing but close OneDrive.

This is further fueling my suspicion that there's something really wrong with my account, but perhaps there's a simple solution.

Thanks!
