This seems like a problem with il2cpu stack analysis. It might be fixed by changes with .net 5.0 but to be sure can you reproduce this issue while using fake classes (so new empty classes, not actual cosmos types), so I can easily reproduce this in unit testing?

I have created the empty classes without using any Cosmos types.

Thank you! Will look into it
