This tutorial video is made in UE4 where the oculus hand component works fine. The problem occurs when you try to retrace the steps he does around min 5:15 in the video: adding the “oculus hand” component in UE5 and then running makes the engine crash everytime.
Unfortunately in UE4 this works fine but not in UE5.
Yes I indeed mean hand tracking with hand motion controllers 
Thanks for the extended help and time effort!
