I was in the team selection screen after I join a server. I clicked on the Skyhammer card in my squad out of curiosity, it brought me to the screen (as seen in the screenshot below) to change the mercs in my squad. At this point I could not interact with anything anymore. I could still hear the in game music and various sounds from the match (people shooting at each other). I had to use Alt+F4 to quit the game.
