Attempting to Reconnect

I just had a game where i was playing at supposedly 75-80 ping but my character would suddenly just stop responding to my mouse clicking. I could easily see the arrows and it was not where everyone froze. It was only my champion that froze. And i could see the team fight and i just watched as my team got deleted and then my character after. Could not react even spamming all my buttons. Fix please. was definitely not client side.
