Villagers Disappear and Do not move after update 1.16.100

Hi there,

today when i played my survival world, something weird happen.

Some villagers disappears and appears from specific place.

Then in the day time almost of them stay still without moving even if i punch them.

Take a look to the video it is very scarry, looks like something bad going to happend haha.

This started after the update 1.16.100.

pd: im preocupeted because it is my first survival world and without the village working as always, maybe can be hard passed the game :c

Let me know if there is something can i do.

Thank you for your time.
