One of my worlds is gone?

So I downloaded the city living pack and have been playing for awhile, so today when I go to play the city living world is gone?? The family is still saved but when I try to call lay with them it says game data incomplete and the reference neighborhood has being uninstalled or otherwise no longer available. And I checked my system it’s still there but not showing up with the other worlds? I’m playing on Ps5 if that helps too.
