UE4 Rendering Completely broke after crash (Help please...)

I was testing stuff in my project and UE4 crashed. Upon reopening my project it looked like this. I verified the engine, reinstalled it, same result. Other projects do not have this effect. I do make regular backups of my projects, but of course this came over a 7-8 hour period of work in which I made stellar progress and hadn’t made a backup. I don’t want to start messing with the settings because I might screw it up further. Someone please help, thank you in advance.

If you check at the top left corner of your editor window, in which view-mode is it right now? Because that picture looks like, the engine switched to the Unlit-Mode (“Lit” is the normal one).
