Unwarranted Crashing

My Minecraft keeps crashing for no reason. At first it wasn't too bad, I just had to restart my game every time I wanted to load a world or join a server after leaving one. As of the 1.11 update, I have been playing for about an hour and a half and my game has crashed around 7 times. The first 5 of which were random whilst I was on my friends' realm. The 6th time I tried to join it wouldn't even let me log on. It just crashed before I could load in the world.

Here's the log from the most recent crash if it helps:
