In most cases, that error is triggered by corrupted Plesk packages that typically result from interrupted update processes. I would suggest opening a ticket with Plesk support so they review the server and attempt to resolve the issue. To sign-in to support and open a ticket go to:
https://support.plesk.com
If you got your license from a reseller, your reseller should provide support for you. If the reseller does not provide support, here is an alternative to get support directly from Plesk
https://support.plesk.com/hc/en-us/articles/12388090147095-How-to-get-support-directly-from-Plesk

Another alternative would be to restore the server from a recent snapshot if such is available.
