The bug

In previous versions, joining a world in which the player is dead would render the world behind the death screen. This last worked correctly in 1.20.1. The next snapshot, 23w31a, started rendering only a few chunks. Then ever since 23w33a, nothing has rendered. This issue has persisted since then.

How to reproduce

1. Enter a world
2. /kill
3. Click "title screen"
4. Click it again for some reason
5. Re-enter the world

Expected results
You should see the area where you died

Observed results
You only see an empty void
