Not loading past champ select [BUG]

It is causing me to have leaver on my match history and i'd really rather not be banned for this bug. I never leave games and I always encourage my teams to do their best. Please fix this bug it's annoying to have this on my history. I really don't know how else to describe it. I don't have any illegal software on my pc. The anticheat is active and on. Firewall is open to league. Please help and remove from my history!
