After the champion select client exits bug (client)

After the champion select timer ends, it should put me into the loading screen, but instead it just goes to the after game screen and i can only click on skip waiting for stats and then the whole game i was gonna play is lost in space for me. Does anyone know how to solve this problem? I've re-installed the client multiple times and it keeps coming back. I've even got a leaver buster now because of it.
