Task fails on self-hosted agent when PSRule and/or PSRule.Rules.Azure already installed

Description of the issue

My tasks were working fine in the Azure DevOps hosted agent.

I just installed the self-hosted agent locally on Windows 11 x64. I already have PSRule 2.2.0 and PSRule.Rules.Azure 1.17.1 installed.

The self-hosted agent runs as the NETWORK SERVICE user.

It looks like it might be trying to uninstall or reinstall the modules, and it's erroring out.

Configuration

Yaml configuration of the extension.

      - task: ps-rule-install@2
        displayName: Install PSRule.Rules.Azure PS module
        condition: and(succeeded(), eq('${{parameters.runPSRuleTests}}', true))
        inputs:
          module: PSRule.Rules.Azure
          latest: false
          prerelease: false

Expected behaviour

Expected it to work as it did in a hosted agent.

Additional context

I tried commenting out the ps-rule-install task, as I already have the modules installed locally.

The next task, ps-rule-assert, failed in a similar manner as it too attempted to install the modules.

I next attempted to uninstall the modules from my machine to see if I could progress. I was blocked again with a similar message that they were in use.

I closed all terminals and powershell sessions and stopped VSCode (in which I have the PSRule extension installed). This seemed to allow me to uninstall the modules and run the job again.

This time I'm getting the following:

Start with the ps-rule-install@2 and ps-rule-assert tasks, using docs/tasks.md for their documented behavior. Reproduce on a Windows 11 self-hosted agent with PSRule and PSRule.Rules.Azure already installed, then investigate the PowerShellGet loading and module-in-use errors. Done means the tasks work with preinstalled modules and produce a clear result without attempting an invalid reinstall.
