Hard Crash on scanning (6000.0.67f1)

Installation
1
  • A* version: 5.4.7
  • Unity version: 6000.0.67f1

I have no idea what is going on, but A* seems to crash when I click on the scan button or call AstarPath.Scan()

I can’t produce a log because it hard freezes the editor at the point where new log messages do not get a chance to flush out to editor.log

How to reproduce:

  1. Create a new project
  2. Install A* Pathfinding Project
  3. Create a new empty GameObject
  4. Click on “Add Component”, then type “AstarPath” and add it.
  5. Click on the “Scan” or call AstarPath.Scan() by code.
  6. ???
  7. taskkill /f /im unity.exe

I was unable to reproduce on a fresh project, but I was able to get into an endless “Hold on” screen by doing it in a blank screen instead of my own game scenes.

Um, any ideas?

Already tried uninstalling, deleting all A*-related files and reinstalling.

My project is using IL2CPP, full .NET API Compatibility, no code stripping and does not use any of A*'s compiler directives enabled.

Update: Disabling burst seemed to turn the hard crash into an endless “Hold On”. As for crashing: it didn’t make any difference whether it was on Mono (C#) or IL2CPP.

Even a tiny LayeredGridGraph (default settings, so 10x1x10) takes 3 hours and still didn’t finish.

Nothing was logged (there doesn’t seem to be any errors/exceptions or null references)

What version of Burst is this on? Actually if you can post all dependencies or even send an empty project that’s crashing that would be great.

Sorry for the slow response, but the version of Burst being used was 1.8.27. Technically none now since I’ve turned Burst off.

I’ll get back to you as to recreating a crashing project.
