How can I serialize an object without getting a circular reference error?

Question

I saw this piece of code in another post, however it was posted 9 years ago so I've made a new post. I am getting the error quoted below when I try and serialize a parameter during runtime. There were a few things I wasn't confident I understood and would like help getting this to work, starting with the error message. A small repro project will reproduce the error each time.

"A circular reference was detected while serializing an object of type 'System.Reflection.RuntimeModule'."
