Since you have the fullname, why not change the assertion message to:
xamarin_assertion_message ("Don't know how to marshal a return value of type '%s', Please Please file a bug with a test case at https://github.com/xamarin/xamarin-macios/issues/new\n", full name);

On a side note, I wonder if this won't be immediately stale with the .NET 6 transition to NativeHandle instead of IntPtr.
