World crashing and exiting the game.

My friend and I have always played with mods/addons and textures with experimental gameplay enabled and we've never had any problems, but in this update whenever we create a world it keeps crashing and simply exits the game. We tried without mods and without experimental gameplay active but the problem continued. This problem also occurs on servers that, in addition to crashing when we call for a "party" to be a group and play together, "social" doesn't work and when it does work, it takes a long time for the option to appear and for us to be able to select who we want to send the invitation to.
