Object Blackboard Unity Crashing Issue

[keelyParticipant]

Hey there!

I’m an instructor who’s using NodeCanvas for teaching a course on AI for game design with Unity. We’re running into an issue where adding variables onto an object blackboard is frequently causing Unity to crash.

Unity Version: 2022.3.41f1
NodeCanvas Version: 3.3.1

If I make a new FSMOwner and try to add a blackboard variable (doesn’t matter what variable type) to the object’s blackboard component in the graph view then Unity completely crashes. If I add it to the component in the inspector then it seems to work fine. If I add it to the graph’s blackboard then it also seems to work fine.

Some students are replicating the same issue and others aren’t. Sometimes I can get the issue to happen and sometimes I can’t.

Let me know if you need more details from my end!

Thanks,
Keely

Hello Keely!

Sorry that these issues happen and thank you for the information you provided. Can you please send me the editor log file after a crash takes place? These are the locations of the editor.log file on various systems (taken from Unity documentation here):

macOS ~/Library/Logs/Unity/Editor.log
Windows XP C:Documents and SettingsusernameLocal SettingsApplication Data_UnityEditorEditor.log
Windows Vista/7 C:UsersusernameAppDataLocalUnityEditorEditor.log

Thank you!
( I will also take a look at this regardless based on the information you told me 🙂

Here’s the log file. I zipped it because .log wasn’t a valid file format for uploading. Let me know if you need anything else.

Any chance you’ve been able to look at this yet? It’s been really disruptive to the class to have this crash happening all of the time for the last three weeks.

Hello again and really sorry for the late reply!
I got another report of a similar crash on that exact same Unity version (2022.3.41f1 ). I tried current v 2022.3.57f1 and everything works fine with no crash. It seems to have been an issue with Unity 2022.3.41f1 specifically that though they fixed since these are the only 2 reports of a crash and are both on 2022.3.41f1. Can you please upgrade to any other 2022.3.x version (eg 2022.3.57f1) and confirm that everything is working fine?

Thank you and once again sorry for the late reply!
