Persistent game crashing whenever I enter a world or load the app.

After updating to 1.13, whenever I enter one of my worlds the game will immediately crash, making the game completely unplayable. Then after updating to 1.13.1, the problem is even worse and I still cannot enter any of my worlds or even load the app without the game instantly crashing less then a minute later. This bug fix update has made the problem even worse than before. I am currently working on a massive map and this is putting me significantly behind schedule. Please fix this issue as soon as possible so I can play the game!!!
