[Powershell] Get-MpComputerStatus returns error

Hello, 

I am trying to get some Information About Windows Defender using the PowerShell Get-MpComputerstatus CMDLet.

But i only get different Errors depending on the System.

I tried this on following Windows Configurations and got following Errors:

- Windows 10 Enterprise 1903 Build 18362.959 (Windows Defender Aktive)

The Problem is, that when i try to use the cmdlet i get following errors:
Get-MpComputerStatus : Fehler beim Vorgang: 0x800106ba

What am i trying to do is to find out if Windows Defender is Active or not.

I wanted to do this with the Get-MpComputerStatus cmdlet but as you already know i get These Errors and i dont know why thes occur.

Help would be Appreciated :D .
