I have tried to use the file for Plesk Onyx to solve this same issue on Plesk Obsidian - and it seems to work.
I did needed to make some more changes though, but that might be particular to my installation. Changing to PHP 8.0 Fast CGI eventually solved the issue, I think WPB's failure to download or restore a snapshot was linked to a specific PHP configuration setting. But in any case, using the solution for Onyx does not seem to hurt Obsidian.
