GAME CRASHED!

My internet **disconnected **while i was selecting the champion in the champion selection lobby. After that, every game has been crashing till now and players in my team I'm afk. Basically, I can't play.

I tried logging in again and re-started my laptop, even uninstalled and re-installed the game again but it's not working. I've also tried the new client and old client both.

Need help ASAP please.
