[CLIENT] Crashing before "Match Found" AFK check displays

I have been running into a bug that has caused my client to freeze up and stop responding shortly before the "Match Found" AFK check appears. This has caused issues with me "declining" games even though I have no control what-so-ever over whether or not I can join the game. I have tried to repair the client but that did not resolve the issue. My computer specs are above the recommended hardware requirements, and my internet is far above the minimum requirements to play well according to speedtest(dot)net. In previous versions of the Client (< League of Legends 6.13.16_06_24_15_03) this was not an issue.
