Error on startup after creating a OdinEditorWindow subclass

Issue #502 resolved

What happened

Multiple errors show up after starting Unity. I haven't seen any ill effects from these errors but they should obviously not be happening. This is what the stack trace looks like:

Recursive Serialization is not supported. You can't dereference a PPtr while loading. (Constructors of C# classes may not load objects either. See stacktrace.)

How to reproduce it

Simply creating a subclass of OdinEditorWindow seems to be enough to reproduce it. Example project included has a very small OdinEditorWindow that reproduces the issue.

Steps to reproduce with example project

  • Open reproduction project.
  • Open the Sample Scene (it's empty, but the errors don't occur when starting Unity with a new scene).
  • Add Odin Inspector.
  • Enable Editor Only mode.
  • Open the custom window (Custom -> Custom window).
  • Close Unity.
  • Re-open Unity and the errors should show in the console.

    This issue resolved itself when I updated from version 2.1.0 to version 2.1.4. Not clear from the Patch Notes what actually fixed it.
