Experienced this issue before but it was maybe a handful of times since launch. Then this week every match has been a coin flip whether I can play a full match or if I have to alt+f4 to close the game.
Have the same symptoms as the other players commenting about the problem. Scoreboard randomly appears and doesnt respond to key or mouse click inputs to exit the scoreboard.
short clip showing tab, escape or clicking on the ui not working to exit the scoreboard:
