Hi
I had to resort to this because I don't know what to do anymore.
Two days ago I was playing in my world of Minecraft with a friend and suddenly my PC went out and then stop playing minecraft. Yesterday I wanted to return to my world and when I enter the world selection screen I find that my world was not. Look in the folder of the game and there was the folder of the world, but within the game it did not appear in the list. I immediately copied the folder in a "backup" form and searching the internet for some methods to return it to normal, none resulted and that is why I am here to please help me solve this problem since that world I play it for about a year.
I await prompt response, thanks

Edit:
I can also load the copy of my world that was in the minecraftWorlds folder so that they try to correct errors.

Edit2:
I thought the answer would be faster, because 2 days have passed and I still have no answer from anyone …

Edit3:
well, it seems that no one helped me here, what a sad service, just thanks for nothing
