Get-ComputerRestorePoint empty

On my W10 Pro 22H2: Get-ComputerRestorePoint shows no results but when I look into System | System Restore I find : System Restore is enabled and there are about 20 restore points.

I rely on Get-ComputerRestorePoint to check, if System Restore is working correctly on my machines.

What might be wrong?

Are you running the Powershell session as Administrator?

Yes - Get-ComputerRestorePoint is embedded in a system which entirely runs as Administrator.
