{Crash} Immediate DC (Remake)

I've just started playing LOL, but now whenever I get on and is about to start the loading screen of the characters, it immediately goes to the reconnect screen. And when I press the reconnect button, it shows "game is still in progress" and goes back to the button. Now i'm banned for literally no reason and I can't play it with my brother. It's not my connection since I checked my connection and played multiple times and never affects me. It's really annoying and I just want to play again. (remake because the first one wasnt "a good bug submission"
