Blocks don’t render on Hypixel and some other servers

When playing on Hypixel or certain other non-vanilla servers, 0 chunks get rendered even though they load in (physics still works correctly). Entities still render. My guess is that it’s either a concurrency issue or an occlusion culling issue that somehow causes every chunk to count as not visible?

I was looking into this before I went on holidays but I can’t really remember what I found. I have a vague feeling that I looked into occlusion culling and it seemed fine.

I had already fixed this in the past but someone encountered it so I opened an issue for it. It turns out that the server was actually just barrier blocks and entities so it was rendering fine.
