I have been playing on a world called weapons expansion in the marketplace and can't play it due to this issue "unable to connect to world, check your internet connection"

I have been playing on a world in the marketplace called weapons expanision and it has blocked me out from playing this world and says "unable to connect to world, check your internet connection", my internet is fine so that's not the problem. I've tried multiple things that could fix the issue such as restarting minecraft, restarting my xbox and signing out of my account and back in but none of these have work.
