Game won't launch some times.

Hello.

I am having an issue where I cannot make it into a game. I cannot find a cause for it and it's not for every match. I get through champion select load up to 99% and the game starts for everyone else, but my just closes. No errors or pop-ups, just sent back to the reconnect in the client.

After this happens if I try to reconnect the game will load up to 10% and then close the game like before. This does say i'm trying to reconnect in game. So i can force my teammates to go through it and lose LP if I were evil.

I don't have any firewall besides microsoft's default one, i've tried disabling it, restarting the client, running the game as Admin, and reinstalling the game. I do not have Avast.

It seems to only happen in about 10% of games, but that's enough to the point where i should probably stop playing until it's fixed.

If anyone has any other solutions to try, or if you have had the same issue then a bump would be nice. Thanks for reading.
