[Undo] Unity crashes when performing large amount of redos that manipulate prefabs
How to reproduce:
1. Open new Unity project
2. In Hierarchy window, create multiple different prefabs, duplicate until you have around 10 in the Scene.
3. Perform various operations that override, apply overrides, nest, unnest, and renest the prefabs (10+). Cyclic nesting appears to make the crash a bit more consistent.
4. Undo some (or every) operations performed by holding down the Undo shortcut keys.
5. Redo some (or every) operations performed by holding down the Redo shortcut keys.
6. If no crash happens, repeat steps 3-4. Rapid repeating seems to make the crash a bit more consistent.
Expected result: No crash
Actual result: The Editor crashes
Reproducible with: 2019.4.0f1, 2019.4.29f1, 2020.3.14f1, 2021.1.16f1, 2021.2.0b4, 2022.1.0a3
