My GetClosestPointOnCollision Compiles but causes UE4 to crash - Help!

Hi, so I think in this project I used a skeletal mesh as root and physics asset for collision and that caused the crash.
I redid this using a custom collision mesh almost the same shape as the skeletal mesh which is attach the collision mesh.
But now I just use hit.location compared to bone.location and I’m doing it multiple times per frame, it works and uses less code!
