I already had a mirror of my Calibre library on a different disk since I use robocopy to periodically mirror it to another drive plus a USB stick for a backup.

I pointed Calibre at the library on the other disk and got the same errors doing the metadata updates:

calibre, version 6.17.0
ERROR: Some failures: Failed to apply updated metadata for some books in your library. Click "Show details" to see details.

The Authenticated Users group has all permissions but Full Control to that sub-directory and lower.

During the metadata update, Calibre is moving the books to a new folder and it is failing on removing the old folder, which is now empty. I was able to use my account to browse into that directory and remove the folders manually in explorer, so the perms have to be sufficient since I am invoking Python in the same account. My real-time virus scanning is fully disabled.
