It would appear that, to retrieve the information you are seeking, PowerShell needs to be run in "elevated" mode (i.e., "Run as Administrator").

When doing so, I see the information as intended; however, when running 'normally' (even though I'm logged on with admin rights), I see the same error message that you have reported.

I'm trying to return the [`Win32_PowerPlan`][1] in PowerShell 7 on Windows 11 with the following code:

```ps1
get-wmiobject -namespace "root\cimv2\power" -class Win32_powerplan
```

However, I get the output:

```none
get-wmiobject : 
At line:1 char:1
+ get-wmiobject -namespace "root\cimv2\power" -class Win32_powerplan
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [Get-WmiObject], COMException
    + FullyQualifiedErrorId : GetWMICOMException,Microsoft.PowerShell.Commands.GetWmiObjectCommand
```

Not sure what could be going on or how to get better error logs.  The [official docs][3] use this exact code snippet, so not sure what it should change to if it's wrong.
