the world cannot be opened

[alparaz]

hi everyone. I played Minetest with a computer (open the laptop). Then suddenly my computer's box died because my house was turned off. Even though my computer's life is still new, it can be used again. can't be opened. then the backup can't be used. whereas the world is my favorite world. so I want to know how to fix it (please answer important)

Nobody here can help if you don't tell us what's in your debug.txt file.

It should mention some sort of error.
