Game Crashes: Cant rejoin comp match?

Just like the title says my game crashed in the beginning of the match for some reason and normally with the rare crash I can rejoin match fairly quickly by relaunching the game, but this time I was not even given the option. What gives?

One of two things have likely happened. You left in the pregame or the first minute of the match (which then the match cancels normally), or you failed to return to the match by the time the match ended normally. Learn more about the leaver system here:
