I received these errors just now when returning to the campaign mission select screen. I just won a campaign, pressed escape and clicked leave game as I always do after a mission. It took me to the screen that you see in my attached pictured. Pressing various keys did nothing, including escape. I had to alt+f4 to force close the game and restart. I'm trying to remember the mission I just completed to give a little more feedback and clues to what might have triggered the exception errors. I've done about 15 missions (Some loses, some wins, some leaving half through) and this was the first time I encountered any kind of error.
