crash when select ranked mode

When I open the game, everything is normal until I select ranked mode. I can play everything except that, because when I select ranked mode, the game crashes and doesn't give me any kind of error message or anything to identify why; it just crashes. It only happens when I select ranked mode; it doesn't happen in any other game. I tried to fix it by repairing the game files through Steam, but it didn't work. I also tried uninstalling and reinstalling it, but that didn't work either.
