unity hub won't let me open any projects i create,Unity Hub won't allow me to open any projects

i have unity version 2018.4.20f1 because i wanted to get into vrchat world building for quest, reinstalled unity and directx as well as replacing a few dll files but it hasn't worked, whenever i create a new project it closes unity hub and doesn't open back up. I open it again and click on the project i created and it says "Project file path does not exist" i try to open up the editer itself and it says "the application was unable to start correctly (0xc000007b)" i'm on windows 8.1 64 bit; my specs are Intel(R)Celeron(R)CPU1005M@1.90GHz, 4 gigs of ram at 1600mhz, no graphics card i have integrated,I have unity version 2018.4.20f1 because i wanted to get into vrchat world building for quest, reinstalled unity and directx as well as replacing a few dll files but it hasn't worked, whenever i create a new project it closes unity hub and doesn't open back up.
