[Client] Will Not Open (TRIED EVERYTHING)

Tried reinstalling it, tried force patching it, and I tried every googled option I could find. NOTHING IS MAKING THIS CLIENT WORK. I PRESS LEAGUE, IT SHOWS LEAGUE CLIENT LOGO NOTHING HAPPENS. I DO IT AGAIN AND OPEN TASK MANAGER AND AFTER ABOUT 30 SECONDS OF THE CLIENT "LOADING" IT RANDOMLY EXITS. I'VE TRIED IT WITH MY FIREWALL OFF, I'VE TRIED GOOGLING IT AND I CAN'T FIND ANYTHING. NO ONES MENTIONING THIS PROBLEM ANY WHERE, RIOT HASN'T MENTIONED IT ONCE AND IT'S BEEN LIKE THIS FOR 12 HOURS NOW.

HAAAALPPPP IM ADDICTED
