Having OdinEditorWindow open when Unity is launched causes exception

[Tim Williams]

Using Unity 2018.2.1f1

If you have any class inheriting from OdinEditorWindow which is open when you launch Unity, you get the following exception and stacktrace 31 times:

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

Thanks, will give that a try tomorrow.

But just a quick question - It's a long-shot. But have you by any chance updated your project to a later Unity version while Odin was in it? If so, try re-importing Odin, and remember to click "yes, I made a backup"

I actually just tried re-importing with the latest version this morning as a debugging step, still got the error after that

This is a duplicate of issue #502 that I created a couple of months ago which hasn't gotten any attention. That issue has a complete recreation project also.
