First occurrence: 1.18.30, reliable reproduction

When both un-rendering or re-rendering nearby areas with many detailed surfaces (lots of trapdoors, buttons, banners, plants, partial blocks etc.), internal game updates seem to freeze.

Steps to Reproduce:

Notes:
It is less likely to happen the lower the render distance is set to. In my demo, I'm using a
render distance of 30 which reliably reproduces this issue for me, my recommended is 48. Render distance of 5 is preventing this from occurring

1. Load a world with many exposed/detailed surfaces, (e.g. over detailed structures) which
are causing frame rate drops, while being in close vicinity
2. Cause those said structures to become un-rendered to save resources (e.g. going below
ground while facing away from it
3. Cause them to be re-rendered, at the moment said occurs, the game stops to function
properly (-> please use video for clarification)

Observed Results:
**Causing any progress/changes to be lost and making the world unplayable for the current
session**
The game won't leave the saving screen upon closing the world.

° Inventory cannot be opened, pick block does not work
° commands (like set time) do not work
° no block updates (carpet and berry bush remain floating after removing their
supporting block)
° Entity's stop moving/lose their collision properties
° Entity's cannot be summoned into the world (e.g. by throwing a trident)
° No particles/ sound while mining blocks
° Particles work incorrectly in general (candle isn't flickering properly when lit, etc.)
