Alt-Tab Fatal crash error Also crashes windows

So Insurgency has always been a little wonky with alt-tabbing and sandstorm is no different. However recently between all the updates from all the software we use something has caused this game to crash hard if you alt-tab in full screen. Nvidia becomes unresponsive and sometimes I get a glimpse of a DX error window' before my monitor no longer reads anything and goes into power save mode. I would like to add I alt-tabbed several other known buggy games like Anthem and it recovers fine.

You might try new game update as we transitioned to UE4.22 however issues like these are in most cases caused by system/driver/hardware instability or by eternal application/malware hooking into the game or otherwise interfering with it.
