Description

It also happens in VR preview in the editor.

Steps to Reproduce
  1. Open the VR Template
  2. Open VirtualRealityBP/Maps/MotionControllerMap
  3. Add stereo layer to VRPawn as written in Docs
  4. Package for windows 64 bit
  5. Create a shortcut of the project exe
  6. Set up the short cut to launch VR
    Right click> Properties > Target > add "MotionControllerMap -VR" at the end
  7. Open the game in VR
  8. Bring up the Steam VR overlay
  9. Exit the application
  10. Notice that the project has crashed and that the crash reporter window has now shown up

Expected: The application would shutdown
Result: The application is exited but is followed up with a crash
