Powershell task without Azure DevOps Extension

[GeofoxCoding]

Hi,

for some reason we are unable to add the *.vsix Extension to our Azure DevOps Server. If we try to open http://our-server/_gallery/manage we get an error:

TF53001: The database operation was canceled by an administrator

So is there any other option to use MagicChunks inside a PowerShell@2 task?

I downloaded the binaries to our build agent and I do the following:

- task: PowerShell@2
  inputs:
    targetType: 'inline'
    script: |
      Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass;
      Import-Module "C:\MagicChunks-1.3.1\MagicChunks.psm1";
      Format-MagicChunks -path "$(Build.ArtifactStagingDirectory)\docker-compose.yml" -type "Yaml" -transformations @{"some/node" = "some new value";}

This gives me an exception in my pipeline:
File or assembly "file:///C:\MagicChunks-1.3.1\MagicChunks.dll" or a dependency of it not found ...

If I execute it on build agents powershell directly, I get even more information:
Transforming file C:\buildagent_work\16\s\docker-compose.yml
Format-MagicChunks : File transformation error: Type[MagicChunks.Core.TransformationCollection] not found ... check if assembly has been loaded ...

From my understanding Import-Module should load everything?
