My World Was Deleted

I play on XboxOne, and I was in a village enchanting diamond boots, then the electricity went out.

Afterwards, I turned on my Xbox again, and when I entered Minecraft again, my world had disappeared from my list of worlds.

What I expected to happen was...

I hoped to enchant my boots with Depth Strider, so I could more easily explore the ocean and its treasures.

What actually happened was...

The electricity went away for a few seconds, turning off my Xbox, however when I turned it on I wanted to finish with my task of enchanting my boots, but I could not.

Steps to reproduce:

1. I took diamonds from my chest to craft some boots

2. I proceeded to go to the village that was nearby, which is where I have the enchantment table

3. Before I get there the electricity goes out and my game shuts down

4. I go back into the game to find out that my world was gone.

I hope you can help me solve my dilemma, thanks in advance
