When I enter the Backup section, I get this error.
Also I noticed that the backups have been stopped for days.

Make sure that C:\Program Files (x86)\Plesk\admin\bin64\pmmcli file has the correct size and can be executed. It looks like it is corrupted. This can be caused by the action of installed antivirus software, for example.

Thanks for the reply. The pmmcli file was 0 bytes, I restored the PMMcli.exe file but when I open the backup List the pmmcli file is recreated again with 0 bytes. Maybe the file to restore is another one?

Do you have enabled any third-party Antivirus software? Try to disable it.

I solved, I write for the next users.
Also in the folder C: \ Program Files (x86) \ Plesk \ admin \ bin there were several files with 0bytes, I proceeded to remove all of them and also the pmmcli file present in the bin64 folder.

The control panel on the Backup List has started working again

Thank you for providing me with this indication, which has allowed me to verify here as well.
