I was creating the world and then exporting it and uploading it to publication. When closed the game I appeared this in the notification bar.
I don't know why that happened. I did the publication before formatting My computer, I went back to install Minecraft when I read your comment to send a world. I'm so sorry for wasting your time. Thank you very much for the attention they gave me, I guess that's it.

Exactly, my current status is 0/94. I have played on other platforms but not with the same gamertag that I have been using to play in Windows 10
Yes, the problem occurs in all the worlds that I have created.
No, there isn't message that achievements in the world are disabled.
I don't have a world without that problem, therefore, I don't have achieved any achievement of Minecraft Windows 10 Edition.
This problem continues to occur in the current beta 02/04/2019
