Minecraft Server disappears after computer crash?

So I have this creative world that I built and play multiple times. When I was playing today with my sister, my Surface 3 died. So I did what anybody else would do, plug it in the charger. My screen went black, but my sister was never kicked out. I told my sister to get out anyway just in case. When my Surface 3 finally turned on, I realized that it exit my minecraft and when I got back It disappeared. I can't find it anywhere, even in my files in my library.

P.S I also have windows 10, but I doubt it did anything.
