Editor crashes if code changes are made when game is playing #9195

Closed eusebiu closed 3 years ago

eusebiu commented 3 years ago

Describe the bug

I noticed that Unity Editor 2020.2 crashes after I make some code changes while the game is playing - it shows the loading dialog with some text (e.g. Application.Tick,... Application.Reload) and then at the end it crashes.

Workaround is to disable the recompilation during play: https://forum.unity.com/threads/editor-crashes-if-code-changes-are-made-when-game-is-playing.1047176/#post-6781571

To reproduce

Steps to reproduce the behavior:

  1. Start an app
  2. Make a change in the code
  3. Wait for recompile
  4. Crash happens
