Client Crashed during Loading screen for RANKED

So the client disconnected me for some unknown reason during loading, and it took down the loading window. Then the client crashed and stayed on game still in progress... I closed the client then it REFUSED to open. It crashed my PC 5 seconds later.

After restarting the PC which took forever, thanks league, I have restore the game and lose LP.

FIX YOUR DAMN CLIENT OR BRING BACK THE FUCKING LEGACY CLIENT SO THAT SHITN WONT BE HAPPENING AGAIN

I have an HP Pavilion with a gtx 1050 4gb... my PC is not the problem. Also I only have league and haste downloaded. FIX UR DAMN GAME
