League exits on it's own but whenever I reconnect it throws me out

So, recently started to play league and everything was going fine, I had decent fps and had almost no lag spikes, but one day when I went to play a game of league and selected the URF game mode because URF just came back. At first everything was going fine and it was normal but when I got to lane and used some abilities it kicked me out for no reason. The "attempting to connect" box never appeared. It just suddenly threw me out of the game. Bug splat didn't come on and so I thought maybe my connection was bad or something so I reconnected and the second I come back it throws me out again. After experiencing this multiple times during URF I found out that if I didn't do anything and just sat at base then it wouldn't throw me out, but if I were to move it would kick me out. After the game ended I played a game of blind thinking that maybe the problem lied with the URF game mode but when I played blind pick I was sent the same treatment. At this point I started to worry and I used the debug program in the league client which didn't help. I then uninstalled and reinstalled league which also didn't help. Getting on the league client is fine but if I were to play a game then I would be thrown out. Someone... Please help.
