Resolution Note:
The first assert (ArgumentException: Slice may not be used on a restricted range array) arises because the QuadtreeHeightSystem script does not have the [ReadOnly] attribute on the CollisionWorld field of the QuadtreeHeightJob struct.
The second assert (AssertionException: Assertion failure. Value was False) arises because the user's RayCastSystem and QuadtreeHeightSystem scripts do not specify a valid filter for the query. They should at least do: new RaycastInput { Filter = CollisionFilter.Default }
