Unreal Engine Crashes on launch

I’m currently having the issue that the Unreal Engine keeps crashing.

Here’s what happens:
I open the epic games launcher, click on launch, the epic launcher minimizes, I get the loading thing, it says initializing 0%, then it closes and opens the epic launcher again. no crash report no nothing just that.

I have already tried:
Verifying the installation.
Reinstalling the unreal engine.
Tried using a different version.
Reinstalled graphics driver.
Tried using a different version for the graphics driver.
Turning off Anti-Virus

None of which have worked.
Hopefully, someone is able to help me.
Thanks in advance.

P.S. Yes I have used it on this pc before without problems

Almost forgot, I did try to open an existing project.
when I did that I got an error stating:
Failed to generate project files.

Can you create a clean project without issues? If you can, then it means Ue4 is fine but something is wrong with that particular project. You are in sadland unless you’ve been using some sort of source control.

However, it also looks you are missing .NET frameworks. Try installing those before tearing your hair out.

No i can’t create a new project, (see the main post).
as for installing .net framworks.
tried that, got this:
.NET Framework 4.8 or a later update is already installed on this computer.
