I have had this issue on a previous world where I got help from support but then eventually it stopped working on the world so I created a new one. I put at least 50 hours into both worlds and now the second world has the same issue. What happens eventually is I save and quit after playing and then the next day that I get on I load up the world and when I move it crashes my Xbox series X with no error messages. When I start up my xbox again and try to load into the world it says “there was a problem loading this world”. I have cleared my MAC address, reinstalled Minecraft, deleted saved data from the game on my console and even hard resetted my xbox. Nothing works. I have an Open NAT type too.  I have looked online and see plenty of people that have had this problem including all of my friends that have the new console and they all have the same issue as me with ONLY playing Minecraft with no solutions online. Is there anything else I can do to make this work or is there an update in the future that will address this game breaking issue on the new console? It makes Minecraft unplayable on the new series X apparently because it happened on a new world I created AGAIN. What’s the point of playing if it will just eventually make every world you create unplayable?
