can't connect to my game after champ select

after finishing champ select, the launcher says "game still in progress" BUT the game don't open. i try to restart launcher, wait for the game to begin ( i was with a friend ),....; but nothing change, so they remake and i get a leave buster of 20min for 5 games :) ( i look to the task manager if the game was open but nothing ). however, their is still a lot of other bugs like when u blocked to the pre-game start but whatever, every game can have unfixed problems, but maybe think about don't punish for remake if the launcher is still broken. ( and sorry if i make mistakes with writting, i'm french ^^)
