This comes from the following discussion: https://discussions.unity.com/t/lowlevelphysics2d-chaingeometry-more-properties-methods-expected/1688135/11
How to reproduce:
1. Open the attached “IN-119159.zip” project
2. Open the “SampleScene”
3. Enter Play Mode
4. Exit Play Mode
5. Observe the crash
Reproducible in: 6000.3.0a5, 6000.3.0b4, 6000.4.0a1
Could not test with: 2023.1.0a1, 6000.3.0a4, 6000.0.59f1, 6000.2.7f1 (PhysicsComposer does not exist)
Note: If the crash does not reproduce, uncomment the [ExecuteAlways] attribute in the Test1 class and try again
