I think the underground buildings will remain missing until

you update away from the buildings below Y0 before updating or use the backup before updating to 1.19.

I am in great trouble because only a part of the pixel art below Y0 is missing.😞

Also, the problem of the underground disappearing is not limited to windows and Android, but I also confirmed it to Switch.

I also suffered damage. Probably, I think that the problem will occur in the world where there is a bedrock at Y coordinate 0 in the flat world.
I think this fix is bad⇩
