This happened to me. I turned off my console and turned it back on. I reloaded Minecraft and waited at the main menu for about 30 seconds until I new for a letter of fact I was logged into my MicroSoft account. When I reloaded the world, I had everything. This has happened twice to me. Once on a creative world, another on a survival world.
