Getting out of VR with Ctrl-Tab causes CTD (Reverb G2)

I have the latest drivers for everything I can think of…still getting the CTD going from VR to 2D for flightsim. Just started to happen about the NVDIA upgrade and the latest upgrader for flightsim. Its a constant issue now…no idea what to do next after re-installing and upgrading all of the drivers…hope they fix this as I really want to fly VR.
