All achievements bugged, can't get a new one.

I can't get achievements in Minecraft Windows 10 edition. I have tried to reinstall it, to restore the store, everything, nothing works. Inside the game if I play with a friend I see the profile picture of my friend, mine never appears, it goes gray. It lets me join my friend's game, but he can't join mine. We both have the NAT Open. An achievement jumped at him and not to me, I can't get a new one achievement. A greeting.
