Collisions in VR will not work

I have been working on a VR project for quite some time now and the last thing I need to do is prevent the pawn from moving through walls. I thought it would be an easy enough task, however after several hours of playing around with collision capsules, boxes, settings… nothing as worked. I think that the problem may lie in the controls and how they are set up. I am relatively new to all of this so any pointers would be very much appricaited.
