Resolved i can't open the backup manager

[Mohammed Belarbi]

Server operating system version

Ubuntu 22.04.3 LTS

Plesk version and microupdate number

Plesk Obsidian Version 18.0.56 Update #1

After the last update, when I try to open the backup manager, it redirects me to the home page with this error:
'Error: 'utf-8' codec can't decode byte 0x9b in position 423: invalid start byte.'

In the /var/log/plesk/panel.log, I found this error:
[2023-10-26 11:39:06.192] 46332:653a4fd9ef6a1 ERR [panel.ui] 'utf-8' codec can't decode byte 0x9b in position 423: invalid start byte

Could you please help me fix this

FYI: I solved the problem by changing the name of /usr/local/psa/PMM/tasks/task.db.
