Windows 10: Minecraft "there was a problem loading this world"

see i play minecraft windows 10 and its been crashing alot recently, though with the new nether update me and my friend decided to look for some netherite but he had to go so i left, then when he could play again it crashed while loading and i had to restart my pc.

then when i tried to join the world it said "there was a problem loading this world" which sucks because we spent alot of time on it.

i saw someone else had the same problem but he was on xbox i play pc and talk to my xbox friend via xbox game bar and app, which if your reading this microsoft i am very thankful because now i can play pc and my friend can play xbox. i have tried all his solutions but none of them work on pc because its different to xbox, please help. -M2T2

Minecraft Windows 10 Edition Lost Worlds

 

Missing world is in my folders but not in Minecraft W10 world list.

I have this one world on minecraft windows 10 editon that disappeared from my world list when my laptop froze and restarted. Upon going back on minecraft, the world disappeared. I've looked in the worlds folder and its still there, but its not on the world
list. What should I do to get it back on the worlds list? PLEASE make sure your answer deals with Minecraft WINDOWS 10 EDITION and not the JAVA EDITION please.

 

Minecraft worlds won't show up on the world list.

So when my laptop crashed while I was playing minecraft, the world disappeared. There was another question on here stating the same thing and one of the replys showed how to get it back. I went on the minecraft worlds folder and it was there but it never
showed up on the list on the actual game. I went back on minecraft and ALL my worlds were missing from the list! So my question is, How do I get them back to showing on the game?
