Error in use(can't create a new world using mash-up templete)

inquire about Minecraft Marketplace.

I bought 'City Living' Mashup from Marketplace on May 14th and downloaded it.

However, attempting to create a new world within Minecraft results in an error.

version in Error : 1.11.2

1.11.3 version was update a few day ago

Error contents is :

Selecting the 'City Living' template when creating a new world will cause a bar-shaped wave to appear for one second before it disappears.

i was be returned to the screen that create a new world.

This error is the same for the next day also

I inquired at the local XBOX Customer Center, but the Customer Center asks me to contact you directly at 'minecraft.net' for Marketplace.

 

Ask is :

How can I solve this problem?

The Mine Coin is already gone.

 

Additional questions :

Can't I share a template that I bought from Marketplace even if I use 'my home XBOX' with another account in XBOX?

The other account is used by my son.

If you can share, ask how.
