A serious issue of entity

When I came back from nether, dogs, horses,  and armor stand with enchanted netherite armors disappeared!!!

I've spent a lot of time to get them!!!!!!!!!

I've paid money for Minecraft. Ok? I paid!!!!!

What were you doing??? 

This is a impossible bug on paid games.

No way.

 

【Details】

・When came back from nether, all of entity disappear.

・When came back from nether, spawn brocks don't work until quit the game and restart.
