Bug 2022.1.0f1 crashing when exit play mode

Not sure what could be causing this - there was a warning that DoTween needed to be updated when I upgraded from 2021.3.0f1 - but this crash seems to be happening after loading the backup level after exiting play mode

Here's what seems to be the pertinent part of the editor.log after crashing :

I'm seeing something similar. I have a bug into Core Support but no fix yet.

In my case, the crashes stopped when I removed a Canvas from a GameObject a couple of levels down the hierarchy from a ScreenOverlayCanvas. The GameObject was a prefab, which I guess might be relevant because Unity also crashed when I removed the Canvas from a prefab. There was nothing exotic I can see about the context.

 

Unity support tells me this is fixed in 2022.1.4 - and I can't repro, looks fixed in that version.

 

Unity closes with "Got a UNKNOWN while executing native code" in the log, in 2022.1.5 when entering play mode.

 

Ignore that - it was my own code going into infinite recursion.

 

I can confirm the same crash happens in Untiy 2021 LTS (2021.3.9f1)

also confirming happening in 2021.3.12f1 LTS, super annoying.

A render texture inside a masked scroll rect caused this crash for me, it just had to be activated once, the editor still crashed even when I close all menus before. my workaround was to disable it completely when im inside the editor.

 

Same here, crash each time on orientation change in Unity 2021.3.21
