I have tried a fresh project with nothing added other than base content, Disabled AV, Disabled Plugins, Removed and reinstalled 4.14, disabled any other startup programs.
Insanely huge issue. 4.12, 4.13 work fine. Was working great before last update. When you try open any blueprint, texture, anything it looks like it will open then nothing, all you get in the task bar is a white window as in the picture. But you cant even see the white window.
Only thing in log when I try open something is:
