I get `Internal error: System.NullReferenceException: Object reference not set to an instance of an object` in the output-generation phase of building a project for Island:

My original target was WebAssembly, but I tried generating a test project for Windows, and got the same error message there. I can share the project privately, if necessary.

This was filed as bug 85000 and fixed, but I still (or maybe again?) get the same error message with this project. This time it is in the Simplifying Code phase.
