Pure virtual function call at PhysicsManager::AwakeFromLoad() Line 1137 causes a crash on a 64bit windows standalone build

-

Steps to reproduce:
-Due to the nature of the crash and the project is a location based VR installation that uses lots of external hardware, it's impossible to test it
-Open the "Crash_2022-07-01_130008470.zip" for the crash dump and player log

Reproducible according to the customer: 2019.4.40f1, 2021.3.11f1

Notes:
-The crash happens when switching from the main menu scene to another scene. The crash only happens on a random basis where switching the scene works well e.g. for 10 times, and then on the 11th time it crashes. The customer has not detected a pattern
-The Customer is loading the scene asynchronously and they are using additive scene loading as well

    I have been observing the same crash repeatedly but not reproducibly in our automated CI tests on 2021.3.5f1 - particularly annoying because a ~10% failure rate in the build automation really causes developer frustration.

    Still no repro, but a strong encouragement to have a close look at the source code. In my experience, pure virtual function calls can typically be identified by carefully reading, in this case AwakeFromLoad(AwakeFromLoadMode awakeMode) Line 1137
