Ok so I have tried possibly everything to get my world converted. I created a few copy saves used 1 on creative and 1 on survival I destroyed everything. Tired to save in the nether. Went to creative set spawn point far away from my world builds still nothing messed with every setting for in game and start screen settings. Still nothing. So I don't think there is a fix for this on our side
If you guys have trouble hover over your world and press Y then send the world to Microsoft.
There definitely will be a update to fix this issue
Nope saving in the nether did not work for me
my freezes as soon as it starts converting I had a old backup of the save I converted that and it worked but it's not up to date with my lastest save
the new update did not fix the issue
