Game crashes when trying to sync old world from Xbox one edition to bedrock.

When I try to sync old worlds from the old Xbox one edition of the game to the new bedrock edition for the Xbox one, it crashes at 9%. If this helps, I was transferring an old save from the Xbox 360 edition. As seen in the picture below, I click on sync for that world, then crashes.

 

EDIT: I now have a video showing what happens
