Game Crashes unexpectedly upon load of world or server

For previous versions as well as this new one, my game has been crashing continuously when I try to load either my own world or a server, this is after the spawn area has been loaded and I see the UI but on a black screen for about half a second. 

I have attached the latest log which is the one on which I crashed and has been happening for the last dozen attempts. I have reinstalled Minecraft to no effect.

I know this might have happened for other users as it also occurred for the previous version, so sorry if this turns out to be a duplicate and I'll definitely help in any way I can if other files are required!

Many Thanks!
