Game Won't Open

After the most recent update, I've had trouble getting my game running. At first, the game would open, cut to the loading screen like normal, but then it would take me to the world selection screen, and when I'd click on my world, it would load only to take me back to the selection screen, and it'd do that repeatedly. Now, the game won't open at all. The game window will open briefly, but then it shuts down again before anything other than a white screen has a chance to load in. I even tried removing all my mods and cc, and it still didn't work. I don't know what to do.
