World won't load

My survival world will not load. It keeps saying: "There was a problem loading this world" I have NO IDEA what I did wrong other than: I use my Riptide III around, 3 Shulker boxes in my inventory, my world is 1.2 gigabytes, its been lagging about prior to saving. Happened since the last 2 updates, PS4 Minecraft version 2.40, Before that no problems...
