Keep files on my device has crashed Windows 10

Mikey63  You appear to have done a lot to your computer, particularly deleting files in what may have been a counterproductive move. Deleting files from a command window while the OneDrive agent is running is probably giving it even more work to do to try to repair sync relationships.

From your description have OneDrive holding more files in total than your hard drive available space: the folders you added plus whatever was there that you asked to be brought down to your hard drive. Was there a reason for that?

I would log out of OneDrive and do some local Windows repairs in Safe Mode before looking at it again.  Other file-intensive processes such as AntiVirus software will amplify any issue you have so disable those

Verify that you have proper backups of your files, as deleting files from OneDrive locally (rather than clearing space) will replicate deletions in the cloud. If your local actions remove those files from Recycle Bin then you may lose files.
