Seems a similar Bug has be reintroduced in current latest release Plesk Obsidian Version 18.0.53
Sad fact: In this "issue" of the bug the workaround mentioned by editing the panel.ini does not work anymore :-/
Please fix - by now no backup is possible on any updated instances (other servers that are still on 18.0.53 Update 3 don't face that problem).
