Crash rendering section: Cannot read field "b" because "$$3" is null

While I was looking around in spectator mode, my FPS dropped to 1, and then the game crashed about 2 seconds later. This has happened 3 times so far in my initial world and once in a world I created to reproduce the bug.

To attempt to reproduce

1. Create a normal world with commands enabled in 1.21.5-pre1 with seed -7453689221233664985 (I also had all 3 experimental packs enabled but this almost certainly does not affect anything)

2. Once loaded in, take a few steps to make the situation match mine as closely as possible (very likely not all of these are necessary for the crash to occur):

   1. Set your render distance to 16

   2. Set your graphics to Fancy

   3. /gamerule doDaylightCycle false

   4. /time set 12500

3. Go into spectator mode

4. /execute in minecraft:overworld run tp @s 1035.82 164.30 -128.40 61.01 21.65

5. Fly around and look around, remaining in the general area that you teleported to, but drifting slightly north and looking generally northwest
   

Note

As the stack traces indicate, I’m using Prism Launcher, but to my knowledge a crash during vanilla gameplay is necessarily a problem with Minecraft, therefore I’m reporting this under MC.
