calibre 6.20. Windows 11

Before "Windows: Make moving files in the calibre library folder more robust, locking folders in addition to files, before the start of the move", I've never had this problem. Can you please remove this?

I'm getting a similar error when editing the metadata. I did not have it open in another program. The contents of the directory has been deleted. I've edited the eBook. Then I delete the original_epub. Then I go to change the metadata. I press the button to update the cover and the other to update the metadata. Then I get the error and boom, files are gone. I've done this twice with the same result.

calibre, version 6.20.0
