Survival World Crashes seconds after loading

This has become worse since the newest update. When I am offline or online, I will open the launcher, click play and load my survival world. After about 10 seconds (usually I am moving about), the screen freezes. I have to click exit to get my mouse to close it. (This may take a couple of pushes to work.) When it crashes when I am offline, if I launch the game again, it shows "Play Demo" rather than "Play". ( I have bought the game.)

The screen still reacts to clicking (i.e. sounds of buttons on screen being clicked.) It has gotten to where I cannot get anything done in my world. :/

*As requested I have attatched the most recent log for a game crash. (Literally minutes ago.).

Note: This is also happening in my Creative world. They are set in the same seed.
