My cats, axolotls, villagers, and armor support along with various armor disappeared

Around 12 pm on October 11, 2021 I played for the last time my version of the world of Minecraft in normal difficulty, before disconnecting, I stayed outside a lair for the villagers where hostile mobs do not have access to kill them, my Cats and armor support and axolotls were in different parts and at 4:30 pm of the same day I decided to return to achieve an achievement that I had forgotten, however upon entering the world I discover that all my villagers, armor supports Axolotls and cats, they disappeared, without a trace,
