5. Attach the script to the Editor
6. Return to the Editor and select, “Enable debugging for this session” in the pop-up window

Reproducible with: 2023.1.0a1, 6000.0.57f1, 6000.2.04f1, 6000.3.0b1

Reproduced on: Windows 10 (user reported), Windows 11
Not reproduced on: No other environment tested

Notes:
- The issue is easiest to reproduce when using Rider
- Sometimes, the Editor will get stuck on “InspectorWindow.Repaint“. If this happens, detach the script from the Editor and start again from step 3
- When selecting the “CrashBehavior” GameObject, a “NullReferenceException: Object reference not set to an instance of an object“ error appears in the Console
- The crash does not occur if line 23 is commented out
