[CLIENT] Cannot lock in during champion select and got banned

I was in the champion selection and when it comes to my turn, I cannot lock in my champion. I hit the button but it kept going back to orange and I hit it again and again and nothing happened. Later, I got a notice that there is an unknown problem and the data has been sent. I quitted and reopen Client and had to wait for 6 mins because I was "abandoned a recent game during champion selection." After waiting, my game had no problem during champion selection at all. After that, I reattempted to play a game again and this time the same problem happened. And now I have to wait for 30 mins which really annoys me. Does anyone have the same problem like this?
