Issue Restoring Database from OPF

[p0lrb3ar]

I am getting this error while trying to run "calibredb restore_database --really-do-it". Calibre v8.12. Restore seems to be creating this folder dynamically. Should I delete the folder right after it's created to see if it can be written again?

I'm having this issue:

I deleted the dynamic folder right after it was created, which allowed it to be recreated at the correct time, and the restore completed successfully. This appears to be a bug.
