Immediately after the update, I created a new game, random seed. Spawned under water in a cave and managed to find a way up before dying. Figured it was a fluke so I tried it with another random seed and the same thing happened, only I was in an enclosed cave with no way to the surface. Died, respawned underwater again. Tried mining dirt for air without tools and then the game crashed. This happened 4 different times.
