Ranked Bug, Again

So I've been having this problem, made multiple threads but basically i'm in champ select, the game basically freezes apart from team chat and i get a penalty for "dodging" and lose LP. I've been having this problem alot lately and no it is NOT my internet connection i am positive of this. Would really appreciate any kind of attempt to fix this because it's difficult enough to climb through ranks with some teamates letalone losing point for stupid reasons.
