Unfair lower priority queue games

I’ve been getting weird games lately, and it’s not my fault. I would get in champ select, and once we load into game, my League of Legends keeps backing out to my home screen, and then goes back into the League of Legends screen, and it keeps going on. After a while, a tab shows up saying something about not having good quality or something like that. It is completely not my fault that I have been “leaving” game. I have a video of whats exactly going on, but I don’t know how to link it or whatever.
