World exporting issue [friend not seeing the world on their pc]

[KenTracer 72]

As the title states, when I export the world and save it, it shows up on my pc when I import the miobject to my project. However, when I sent the miobject to my friend, the world is invisible and get a message saying "could not import from world, it might be deleted or moved to another location. I even sent them the entire project and it still didnt work, same message.

 

I've been trying to fix this issue for a while now and nothing works. I even sent them the world and placed it in their save world folder and it still didnt work. 

 

Is there a work around? Schematics from 1.13+ doesn't work, exporting doesn't work, so is there no work around?

Just to know, did he open the world you sent him in Minecraft and preferably in the version of Minecraft (Java or Bedrock and the 1.13 or others) you made this world to avoid problems ?

Maybe it doesn't work because the world isn't completely loaded on his/her session.
