[Error] Resolve on invalid GC handle spam

[wrymnParticipant]

This happens immediately when entering the play mode and selecting one of the graph owners running in a scene hierarchy and opening the Canvas editor window (or having it open beforehand).

 

Steps to reproduce:

– enter play mode

– open Canvas editor window

– select of of the Behavior Tree Owners from scene hierarchy, or any Behavior Tree from the Project window.

 

Unity version: 2022.1.16

CanvasNode version: 3.2.5

Platform: running MacOS on latest Monterey

I’m also getting this error, same Unity and NodeCanvas version as OP, I’m on Windows 10 though.

I’m also getting this error, but I’m on Unity 2021.3.9f1, and NodeCanvas version 3.2.1, on Windows 10

Hello,

It seems like a Unity bug introduced in Unity latest versions regarding GUILayout.Window. Simply calling GUILayout.Window (on a fresh project and a new editor file), makes that error to show up and is thus irrelevant to NodeCanvas or any change made to it. I will report the issue to Unity and hopefully they will fix this since it is related to the fairly common GUILayout.Window method.

Okay, thank you, hopefully they will fix it.

Will you be able to keep us posted with the status of the bug report from Unity and let us know what they say/do about it?
