Computer Hard Boot Required on Game Exit

Upon exiting the game after a couple hour play session all my monitors went blank/black and there was nothing I could do to get back to the normal Windows UI. No key commands seemed to do anything; Ctrl-Alt-Del didn’t work. I had to hard reboot my computer. I have played the game a few times for similar lengths of time and not had this problem before.

I attached the player log for you to look at. It’s the player-prev.log. I didn’t know not to start the game client before attaching the player.log. Thanks for any help you can have with fixing this.
