Unable to pick champ during selection

Hello, I just recently encountered a bug where I was completely unable to pick a champion during the champion selection. It doesn't seem to be connection error as other players were telling me to pick a lane as the timer goes, but I could not pick a champ at all. As a result, I got booted out and lost ranked points due to a bug, which wasn't fair.

I'm not expecting my LP to be recovered, but I want this bug to be fixed as soon as possible because it really bummed me out that I lost LP and forced to wait 5 minutes till next queue.
