Crashing in ranked champion select

So lately I've been trying to climb the solo q ladder, however I would come across this unexpected crash during champion select. It would occur during the banning phase, one ban after another. (Just went into queue again and it happened after the 6th ban) my client would randomly not respond; and if I were to be one of the players who needs to pick a champion early during the drafting phase it would result in me dodging which is not what I intend to do. It has been happening quite frequently, and I've tried to restart the client but I find that it would still occur, I'm sure it has nothing to do with my wifi but I have no clues as to why it's happening. Currently I don't want to lose lp that for something I can't control. Dodging once is fine, but having the game dodging multiple times hurts the lp that I've gathered through games.
