Backup bugs made in previous updates
Before January 2021 I ran a server on the site "aternos.org" (which, by contacting them privately, they advised me to report the bug). My last backup, I had saved "world.mcworld", and lately I was about to reopen it, but in the current version of Minecraft, the server starts but Minecraft won't let me in, giving me "Can't connect to the world".
Environment
Online platform, which manages the server
