Champion Select Issues (blind and dynamic queues)

Today during most of the games I have encountered an issue with selecting champions in the champion select process. It has happened in both blind pick and dynamic queue. When selecting a champion, it will either take a while to show that the champion has been selected or not select anything at all when I click and result in a queue dodge. It might also be note worthy that I sometimes could not select summoner spells or ward skins when this would happen.

I also have had some Issues in game, mostly minor delays in registering the last hit of minions, and delay in the use of abilities and occasional lag in my movement. My ping hasn't changed, and my brother who has been playing on the same connection has not experienced any issues with the client or game.

I have tried repairing the client but I am still having issues, is there anything else I can do to try and fix this?
