I also have not been able to enter game since about 9 pm EST last night May 28th. I am in a modded server The Purge - Deer Isle. I see the Deer Isle loading screen with red bar at bottom and when finished it kicks me to Windows with error - "Exit code : 0xC0000374 - STATUS_HEAP_CORRUPTION". The person I was playing with did not get kicked and there was one other in the server unaffected.
