Undo crashes Unity with segmentation violation SIGSEGV

Scene Management


Reproduction steps:
1. Open the project attached
2. Open the scene "SampleScene" (Assets/Scenes/SampleScene.unity)
3. In the Hierarchy window, select the GameObject "Test"
4. In the Inspector window, click the button "Duplicate1"
5. Undo the action (Edit > Undo Create-Child)

Expected result: Unity does not crash
Actual result: Unity crashes

Reproducible with: 2022.1.0a12, 2022.1.0b2
Not reproducible with: 2019.4.33f1, 2020.3.24f1, 2021.2.6f1, 2022.1.0a11

Tested Mac and Windows

1. The Editor log is attached but it does not contain stack frames (only information that the crash was caused by segmentation fault)
2. The issue is somehow tied to the Asset used, because this does not happen in a new project when doing undo on a duplicate cube in a new project

    I am pretty sure this Is also happening in Unity 2021.3.10f1.

    Anytime you undo a duplication it crashes.
