My minecraft world got corrupted

I think your best option is to trying to upload it on another console if possible. More than likely the game was either syncing or saving during the crash and that caused the corruption. Same thing happened to me about a year ago on a world I had spent about
100 hours on.

It looks like the game has been needing a severe update if anything u may need to uninstall it for a bit then reinstall.

I dont have another console so what should i do?

Im afraid you wont get it back.

You can re-install the game. That MAY reinitialize the save and recover it. Since its cloud based, it might work. If that doesn't work then it may be gone for good I'm afraid.
