How to reproduce:
1. Open the attached project "My project.zip"
2. Open the "scene" Scene from the Project window
3. Select "Object1" or "Tree" in the Hierarchy window
4. Add any component to the selected GameObject
5. Undo and redo the action
6. Undo and redo the action again
Expected result: No crash
Actual result: Crash occurs
Reproducible with: 2019.4.33f1, 2020.3.26f1, 2021.1.0a1
Not reproducible with: 2021.1.0a2, 2021.2.9f1, 2022.1.0b3, 2022.2.0a2
