*FIXED*
Issue found linked to corrupted install. Verify game files in Steam indicated a problem that required an update install. However game would not update. Deleted game then re-installed, now works perfectly. Issue must have occurred during Bootcamp update.

Having completed the first (VR) mission in Bootcamp the player character is unable to move after turning away from the laptop and being told to go and fix the falling plate target. The game world continues to function but it is simply not possible to move in any way. I've tried playing Prologue through from the beginning again and I realised that the targets that are supposed to appear during the initial VR phase don't, there's just yellow box markers on the ground where they're meant to be. {F24792}
