I had this happen to me twice. When I was queueing in unranked PvP and the screen ‘accept/cancel’ for starting the match came on, I accepted, then choose a map. Then a NEW ‘accept/cancel’ screen came on. The first time, I could click ‘accept’ again and could again choose a map, which resulted in the first printscreen. The second time, I couldn’t click ‘accept’ nor ‘cancel’. I also couldn’t escape anything on my screen so I had to do an alt+F4 (second printscreen).
