NullReferenceException on PSShouldProcess Rule.

Before submitting a bug report:

• Make sure you are able to repro it on the latest released version
• Perform a quick search for existing issues to check if this bug has already been reported

Steps to reproduce

I’m using PowerShellBuild and my module was made with Stucco.

I haven’t changed the template. And the Analyze task was working fine yesterday.

I can’t give steps to reproduce yet, working on it. Could I send someone my zipped module ? Not ready to make my code full public.

If an unexpected error was thrown then please report the full error details using e.g. $error[0] | Select-Object *

I will need to install it.

Gonna spin a vm to try.

Final edit I had my module still installed. (That damn PS5 bug with the classes) Removed it, made sure it wasn’t installed anymore. Closed VSCode. Reopened VSCode. My Analyze task now works, no PSSA errors.

Thanks again for your help and patience.
