James,

1. Minecraft (Bedrock) uses the Xbox Live service to connect to friends in online worlds if you are signed in with your Microsoft Account. You and your friend may need to forward ports in your routers' settings so your device can communicate with other devices
   using Xbox Live.
   
2. Make sure you are connected to the internet.
   
   Perform an internet connection test on your device to find out your NAT type:

3. If you have a moderate, closed, or restricted NAT type, open ports (port forward) for Xbox Live in your router's settings: https://beta.support.xbox.com/help/Hardware-Network/connect-network/network-ports-used-xbox-live
   
4. Verify you aren't using any multiplayer-restricted skins or other resources both when hosting and joining.
   

This is a common issue with Minecraft on all platforms. According to Microsoft, it's an issue with Mojang and how worlds are synced to the cloud. Another possibility is that your world has been corrupted (often due to connectivity issues while syncing data).
Your only option may be deleting the corrupted world.
