Windows Essentials Server 2016 Service for Client Backup not run

Hi!,

After the windows update KB5028169  does the service for "Windows Essentials Client Backup" not run.

When I start the service manually, it immediately stops again with the following message "Service 'Windows Server Essetials Service for Computer Backup' was started on 'Local Computer' and then stopped. Some services are automatically stopped when not in use by other services or programs. " (Original in German: Dienst 'Windows Server Essetials Dienst für Computersicherung' wurde auf 'Lokaler Computer' gestartet und dann angehalten. Einige Dienste werden automatisch angehalten, wenn sie nicht von anderen Diensten oder Programmen verwendet werden.).
In the event log there is only one entry about starting and one for stopping. No error messages at all.
Restarting the server - without success.
Uninstalling the update - without success.

Any idea?
