Transform corruption and/or crash on PhysX::CreateCharacterController when spawning physics objects into Prefab stages

Steps to reproduce:
1. Open the “user’s attached project.”
2. Open “SampleScene”
3. Enter Prefab Editing Mode for “PrefabStage” through the Hierarchy
4. Change the Scale of the “PrefabStage” GameObject through the Inspector
5. Undo the changes
6. Observe crash or “Invalid AABB” errors printed in the console

Reproducible with versions: 6000.0.65f1, 6000.3.3f1, 6000.4.0b3, 6000.5.0a4

Notes:

• The crash is inconsistent and can be triggered through different scenarios, but freshly extracting the project before every reproduction and following the reproduction steps mentioned above seems to get the most consistent results
• May need to reset the scenario as the corrupt transform can get written into the scene. To do this, open the “PrefabStage” Prefab, disable and enable the Spawner.
