Game Crashes in Loading Screen, Cant Reconnect (Riot Please Respond)

As soon as I get into the loading screen of a game, I get the error message "The application was unable to start correctly (0xc0000005). Click OK to close the application."

This happens whenever I try to reconnect to a game also.

The only thing that has changed on my computer is the newest Windows 10 update, KB3144756

Any fixes? I can't play the game.

Edit: I fixed it by disabling AVG. :)
