on Aug 30, I was having the same issue so I restarted my computer which made it work and I was able to play a game.
next day Aug 31 after the hotfix I tried to start the game but this issue came back. I have tried verifying files, complete reinstall, several restarts, driver updates, running as admin, and launching in windows 8. Nothing I have tried has made a difference this time. There is no variability between crashes, they all happen at exactly the same moment.
After crashing I am greeted with the unreal engine report thing with seemingly no specific information on it
