I downloaded Minecraft for the first time on Saturday, and everything was working fine until a few hours ago. Now, whenever I try to open a world, the game crashes. I'm running version 1.11 on Windows 10 (64-bit). I've checked some 1.10 guides, but nothing seems to be working for me, I changed the VBOS settings, I've completely deleted .minecraft and reinstalled it, but it keeps crashing.
The crash report is as follows:

Any help would be greatly appreciated!
Generally speaking this is a firewall issue.
Something is preventing MC from opening a loopback socket for the client and internal server to communicate over.
