[Client] freezes during champion select

[Client] The client occasionally freezes during champion select. Sometimes it recovers and other times I get a loss because I get disconnected from PVP.NET or I "failed to pick a champion." This has happened in several ranked matches. I added a screenshot. In the screen shot, you can see the first ban (Gragas), but the summoner banning is still banning ( gray highlight with "banning" next to them) in the client and there is no timer left.

I honestly have been dealing with this for a while now, but since it hasn't had a big impact on my ranked queue, until now(three losses in a row). I figured I would bring it up.

I have tried everything on the first page of google when I searched it still never helped. I keep my Adobe Air up to date as well.

[Gameplay] Also, since 5.9 I have been getting unbearable lag on NA servers. I have ~80-90 ping, but the game animations will freeze. Health bars will still be accurate, but nothing is where it seems to be. It reminds me of rubber banding in a FPS.

I have even tried reinstalling LoL, it didn't help
