Queing for an OverWatch game

I was in que for support on comp and I must have entered a game at the same time as going back from the main menu to the role selection page because my game bugged out. I was left on the role selection page and the game started, it counted as me leaving even though I was unable to see what else was going on, it counted as me leaving even before I entered the next screen of the players in the game and the map, I was still able to use the team/match chat and someone said “do we have a leaver?” and I was able to type back saying “my game is bugged still in the role sceen” I’m not sure how this could have happened I possibly could have lagged out while this in the game and I’m not sure if this has anything to do with it but I was using an xbox controller.
