Crashing in loading screen (WHEN WILL YOU FIX THIS RITO PLS)

So with the new client, there's been a bug where you crash/bug splat in the loading screen for seemingly random reasons, and I have no clue why. I know it can be caused by having steam open or alt-tabbing, but holy hell this is ridiculous. I LITERALLY GOT LEAVER BUSTER FOR FIVE GAMES BECAUSE I KEEP CRASHING IN LOADING SCREEN. I have failed to connect to ONE GAME. Only ONE. And that was a ranked game that is now a free loss in my provisionals. So now I'm going to have to wait for more than likely up to an hour in total for the next five games because of this garbage new client. I literally changed none of my settings, everything is the same from yesterday, where I could connect fine, but because I failed to load into ONE GAME because of your garbage new client forced down our throats when it's not even complete, I have to waste time in a leaver buster I didn't even deserve in the first place. What the hell Riot. When I clicked reconnect, the game would load, and then close and go straight back to the reconnect screen. So thanks for the broken garbage forced down our throats for no reason. You have a public test environment, and your own developer mode, so use it! Come on! The new client has been out quite a while and these bugs that completely destroy someone's experience with the game haven't been fixed at all.

EDIT: system specs if you need it, more than likely irrelevant though considering you just pushed a broken product.
