Why is Unreal crashing when I launch?

It was working perfectly about 2-3 weeks ago. Last night I try to open Unreal and it crashes every single time. I have uninstalled and installed it back two times now. I have version 4.4.3 & 4.3.1. None of them work and none of my existing projects work. I click launch, it loads the little rectangle loading screen for a second and it crashes. This is the report:

Maybe try this?

Hey Luquid XI, can you upload the crash log, dump file, and dxdiag? This thread says how to get them.
