We know about the issue and currently looking into fixing the problem. It has something to do with getting the VR device in code and we are trying to pin-point exactly why/where it happens. The fix will come soon.
If you are currently thinking about buying the game, but not sure, we suggest you to add the game to wish-list and wait for an announcement about the update, which will fix any major issues with the game. We would like to provide our players as smooth experience as possible, so please be a little bit patient.
