Create or loading world gets stuck on "Building Terrain" forever

I have been running Minecraft 1.11.2 for a while and everything works fine. But today it suddenly stops loading my terrain. It got stuck on "Building Terrain" forever. I tried to create a new world in single player mode. Same thing. So I uninstalled minecraft and deleted .minecraft folder. Download the latest 1.11.2 version and reinstall it several times. Still the same error.
Here is the output file when it gets stuck:
