No projects open at all

So I have been having this problem for a few hours now (About 6-7 hours). For all my projects, even just opening the editor, in general, it initializes to 73% every time then closes that screen, and the editor never opens, so I checked task manager and sure enough, that project was open in task manager. So I restarted my computer and tried other things and nothing worked. Also, I tried opening other projects at the same time but they just popped up in task manager never on my desktop. I really need help because I have a project due and I wanted to make something cool with UE4 but now I can’t :_(, thank you for ur help
