Regression

Crash on UndoManager::RegisterUndo when attaching a script with MonoBehaviour.Reset() function that changes the GameObject's properties

-

Reproduction steps:
1. Open the attached project “CrashRepro“
2. Drag ”Assets/NewScript.cs” on “TestingObject“ in the Hierarchy window

Expected result: Script gets added to “TestingObject“ or an error is thrown
Actual result: Editor crashes

Reproducible with: 2022.1.0a12, 2022.3.3f1, 2023.1.1f1, 2023.2.0a20
Not reproducible with: 2021.3.27f1, 2022.1.0a11 - “Can’t add script 'NewScript' to the GameObject 'TestingObject' because it has destroyed itself in Awake or OnEnable“ window appears

Reproducible on: Windows 10

Note: Editor does not crash and throws an error when resetting the attached script component from 2022.2.0a3 and above

  1. Resolution Note (fix version 2023.3.0a13):

    Added detection within AddComponent of scripts that potentially destroy the object during Reset.
