Experience bar freezes and also duplicate items sometimes

At the beginning when I play minecraft everything is normal after a time already advanced in the game the experience bar freezes at one level and the experience orbs stop giving experience sometimes I try to restart the application and it duplicates the items and the problem of the experience is not solved even if i die it is still frozen and only the large orb gives me experience and it continues to freeze in the image that I put it of the lapis lazuli doubles for me from 8 to 64 and I also kill mobs but it does not give me experience at all and the weapon mine that has mending it is seen that nothing is recovered
