Invalid namespace in PowerShell working with FSRM

Trying PS command:

Set-FsrmFileGroup -Name "Anti-Ransomware File Groups" -IncludePattern @((Invoke-WebRequest -Uri "https://fsrm.experiant.ca/api/v1/combined" -UseBasicParsing).Content | ConvertFrom-Json | % {$_.filters})

Getting error:

New-FsrmFileGroup : Invalid namespace
At line:1 char:1
+ New-FsrmFileGroup -Name "Anti-Ransomware File Groups" -IncludePattern @((Invoke- ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : MetadataError: (MSFT_FSRMFileGroup:Root/Microsoft/...T_FSRMFileGroup) [New-FsrmFileGroup], CimException
    + FullyQualifiedErrorId : HRESULT 0x8004100e,New-FsrmFileGroup

I also notice some errors in FSRM:

Firewall is off and I am domain admin running this as admin. SFC and a WMI repair came back as good. I am going based off a guide (https://fsrm.experiant.ca/). This has worked across a ton of other servers so I don't believe the commands to be improperly formatted.

Output of Get-WmiObject -Namespace 'Root/Microsoft/Windows/Fsrm' -List:
