I have the same issue (and in the Open Beta), Tried every standard troubleshooting step.
For me the game launched from initial install absolutely fine, I played for 2 hours and decided to restart my computer, now it won't launch. This is the same experience I had for the open beta. I even tried deleting the local files/settings etc. to see if that was causing issue and that didn't change anything either.
The only way I got it working is to reinstall windows and even then, it still won't launch after the first time.
