[CLIENT] Unable to choose champion

So ever since the last patch there have been some buggy moment with when i need to choose a champion for either locking in, banning, or saying i want to play them. The most recent time this happened was in a ranked game and i could not indicate what champion i wanted to play because the list of champions did no pull up. At that point i was to it since it has happened to me many times before then. When it changed to the banning phase the list of champions was pulled up and i could ban the champion i wanted. Afterwards, i was first pick and list of champions did not pull up no matter what i did. I clicked around to see if the list was invisible, but nothing seemed to work. This ultimately forced me to dodge another ranked game.

I am unsure how to repeat this bug.

This bug occurs often and only now did it not allow me to lock in a champion. It usually made it to where i could not indicate what champion i wanted to play.
