This is mostly caused by the recent changes of large files in the computer, such as hard disk formatting and disk segmentation. You can try the following methods to solve it, which may not help.

1, slide the mouse to the upper right corner of the screen, click Search, enter the file history settings, and select the file history close button. The document history here is of little use in most cases. It just copies your desktop, collection, library and other content to your hard disk. I think so, too. Of course, I may be ignorant and have other functions.

2. If "file history" must be started (there is such a perfect person, pliers-I must "how, how"), then prepare a slightly larger U disk, also find "file history settings", select "other drives" in it, and select the drive letter of your U disk for about a few seconds (don't pull the U disk at this time, copy it.

-My opinion.
