Why aren't minecraft achievements working for me?

Hello everyone, I recently installed the game Minecraft Windows version, since I wanted to complete all the achievements of it, at first everything was going well, since I could complete all the achievements without any problem. The problem comes when I suddenly can't complete the achievements anymore. It is important to say that I have never used creative or tricks in my world. Even so, I created a new world to see if it was a problem with the world or something else, I'm just about to perform an achievement as simple as getting iron armor and the achievement doesn't pop me. I have already looked at many possible solutions and I cannot solve it.

Thank you very much to all.
