UE4 opening "empty window" on win 10

Hi so this problem started a while ago when one of my files refused to open, tested things some more and truns out that all new files created will do the same (opening an empty window)

ive seen that many ask for a dxdiag so i will also provide that
i am using UE 4.21.1
and windows 10 pro 1809
