minecraft windows 10 edition multiplayer error unable connect to world !

You need to be more specific about your error your having. what world are you trying to connect too?

... I am transferring a Minecraft world from xbox one edition Minecraft to Java edition and Windows 10 edition.

The Minecraft Xbox One Edition only works on the Xbox One Edition.

You might want to upgrade to the Minecraft (without Xbox One Edition in the name) on your Xbox. If you bought Minecraft Xbox One Edition digitally, you can upgrade to "Minecraft" for free.

Then you can import your world from the Xbox One Edition to "Minecraft" for Xbox One.

However, the Support page for Windows 10 Minecraft states: "The Windows 10 Edition does not currently support the transferring of worlds from other devices."

So you can't transfer your world between devices.

You might have to move your World to a paid online Realm server to access it. Or you might have to run your Xbox One Minecraft in Multiplayer, and connect to the running world on your Xbox One with your Windows 10 version.

But you can't have your World separately transferred from Xbox to other devices.

As I said, you can try hosting your world on a Realm server (which you need to pay for), and can then access it with Windows 10, Xbox One, Android, iOS and Nintendo Switch.

But not JAVA.

You should try restarting the computer and the game. If you still receive the error message, you may need to remove your friend and then re-add him/her back. Then check if you can connect to your friend's world. (This is for your friend) If this doesn't work I recommend checking out this post.
