Consistently crashing on loading screens - can't play any games

Anyone else been consistently crashing on their loading screen? Ever since this latest patch it happens to me pretty much every game (I somehow managed to play a game of 3v3 last night but other than that its every game without fail). Champ select is fine, but when it goes into the loading screen it hits a certain percentage and boom....bugsplat.

I haven't hit the low prioirity queue yet but it's getting so frustrating. i don't know what to do; I tried the 'initiate full repair' tool, I even completely uninstalled and reinstalled.

Anyone having similar issues with any fixes?
