Dump error?

I go to play a quick game of Aram, go past champ select and into the loading screen, it crashes and gives me a dump error and WILL NOT allow me back in. Any fixes? Anyone else having this issue with anything on the game? This is literally the first time its happened. It was fine last night and today it had an update which I'm assuming caused it.

Edit: Everytime I go to reconnect it just doesn't go past that "Reconnect" button and won't do anything.
