Corrupted data

While playing MC on the PS4 console, I played in my singleplayer world. I was in the Netherlands and when I decided to leave the Nether forthrest, there was a power failure and at that moment the MC fell together with the PS4. Since then, I can't get into my world, and it shows me in the folders that the data has been corrupted. And I couldn't back it up because I didn't have a PS plus and I couldn't save and upload my world file. I don't know what to do to get my world back.
