Editor freezes when saving scene

Unity Engine

When saving the scene in Unity 2022.2.17 (apple silicon) on m1 pro macOS 13.3.1(a) the Unity Editor freezes relatively frequently (every 30~ minutes). Unfortunately because it’s a freeze and not a “crash” there is no Unity bug report window I can fill out.

When I force quit the frozen editor after a few minutes the Mac crash reporter window gives me some information. I don’t really know what to do with it, and it’s super long with hundreds of pages of stack traces etc.

It does mention the Unity Hub though Responsible: Unity Hub [76301] [unique pid 374398], but I don’t know what that means.

I tried moving up to 2022.2.19 but it didn’t help unfortunately.

It seems when I save the scene the changes are saved because when I relaunch all my changes exist, some somehow it’s happening near the end/after the actual data on disk part. The UI never updates to reflect though, the asterisk is still shown next to the scene name above the hierarchy window.

I have found a solution. It might be too late though. This is a bug present only on MacOS, if you have VSync enabled in game view the editor pretty consistanly crashes when:

  • Saving scene
  • Reloading script
  • Entering/exiting play mode

To avoid crashes start play mode, turn on vsync, play test, turn off vsync and stop play mode. I hope this helps!
