I need help with Minecraft Bedrock Edition

[RedHeadAngel]

So, I've been playing on my Xbox and PlayStation ever since my PC died. Yes, I play all 3. What of it? While it's been nice to go back to my console games, I've encountered a strange and irritating problem with Minecraft on my Xbox. On some of my worlds, I can't launch them because I get this error.

 

 

This doesn't make sense because these worlds worked just fine, even after the latest updates. Also, a few of the worlds being plagued by this were made recently, so I can't do what the error is suggesting. I've looked everywhere else to find a solution but found nothing. Hell, going on Reddit to find a solution was about as effective as performing brain surgery with an 8-gauge shotgun. Is there some way to fix this, or am I screwed?
