[NEED HELP AF] Horrible UE4 Editor bug!

[I’m not native English speaker]
Hello everyone! I’ve got really horrible problem! I am working on project and I planned to publish it this summer, but it messed up!

So, I opened my editor next day and I saw my editor is fully black! Its black, but I can interact with it as usual. I see nothing. I’ve tried to reinstall engine - nothing’ve changed. Idk what to do! i dont want to reinstall Windows but this is my last option. Maybe you guys know what to do. I’m literally shaking. Need your help

do you get the black screen with just that specific project, or all projects?

To all projects. Even on different versions

is it just the 3d viewport that’s black, or everything?
I’m pretty sure you meant everything, but i’m asking in case the pic you took is your game in full screen.

you’ll want to make sure the graphics card and cpu drivers are up to date. that’s almost certainly not going to solve the problem but it can’t hurt.

you could also try playing a game built with the ue4, since if it works that points a bit more to an issue with the engine rather than something wrong with your computer.

I REINSTALLED WINDOWS AND EDITOR DOESN’T WORK AT ALL. IT CRASHES EVERYTIME I WANT TO OPEN MY PROJECT!!! WTF??? I DONT HAVE MUCH TIME!!! AAAAAAA
