100% CPU on Launch (Crashes)

It won’t let me edit my post anymore but this is how it should read:

I am trying to open a new project but I can’t open any projects bc it crashes my desktop moments later. All of my cores go straight to 100% and my cpu hit 83c then my pc blue screens. Usually during compiling of shaders upon opening a new project, as it’s counting down from 1000 something but about halfway the count freezes and it crashes. What gives?
