Xbox one World Conversion - Fails at 33%

Hello

I have been having issues converting my worlds over to the new Bed Rock Edition ( Better together update)

Since Xbox one is going to be discontinued - I am able to convert a world that is 158MB in size but my newer map that i am playing on is only 113 MB

When i start world conversion is syncs up fine, but the world conversion bar only gets to 33% then closes the Minecraft (Bedrock Edition) game and dashboards me

I am unable to convert my world over at all.

please let me know how to fix this
