Unreal crash 4.25 when importing.

[ShadowOps]

Using latest version of ProjectExodus - Unity version 2019.4.3f1.

Edit2: Seems if the object/mesh/prefab has a Mesh Collider + a box collider the import in UE4 fails. I removed both and exporting/importing the group went fine.

Similar problem, but in my case it was UE4.24.3 that crashed.

@genemiller This appears to be a different problem. I've created an issue for it. Thanks for the data files, be aware, however, that they're public.
