Hey guys!
I was importing texture to a mesh when suddenly my laptop crashed. It's been 10 minutes and there were no sign of it coming back so I force shutdown it by holding the power button. Now, I'm trying to get back into the project but the display somehow got messed up!

Everything becomes dark, no sun. This was how it used to be (I took a screenshot some time ago for something)

Opening other projects & creating new ones aren't affected. They all display normally except for this one project. How do i fix this? I don't want to make it from scratch again :s
