This is not a regression. Tested in //UE5/Release-5.2 CL26001984
The editor crashes when a physics asset of an animation with rigid body collides with geometry collection.
Expected Results:
The pieces react to Character.
Actual Results:
The Editor crashes with an Unhandled Exception
Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000010
