Black screen after initialization on 4.18.2

So, when i press launch on the Epic Games Launcher it begins to launch UE4. Everything is normal until the initialization process is completed. instead of loading up the project screen giving me the option to start a new project or resume an old one a black bar appears in the place that this window should be. I do not know what is causing this, i have restarted my computer 3 times and have reinstalled. Please respond if you find a way to fix this issue.

i am not an expert but i have this problem and i uninstalled my vga driver and the unreal engine back to normal
