When a collision enabled RBAN node attempts to collect surrounding meshes, if there is a mesh with UseComplexAsSimple, it will hit the Ensure when cloning a mesh on the task graph thread.
Disabling "Use Multi Threaded Animation Update" is a work around.
Ensure occurs with a log :
ensure condition failed: IsInGameThreadContext() [File:D:\dev\UnrealEngine-5.0.2\Engine\Source\Runtime\Experimental\Chaos\Public\Framework\Threading.h] [Line: 243]
