USER ERROR: FATAL: Index p_index = 4294967294 is out of bounds (count = 32772). at: operator[] (./core/templates/local_vector.h:161)

### Tested versions

- Reproducable, though I'm sure this is a rare instance lol.
Godot 4.2.2, Forward+

### System information

Godot v4.2.2.stable.mono - Windows 10.0.19045 - Vulkan (Forward+) - dedicated AMD Radeon RX 7900 XT (Advanced Micro Devices, Inc.; 31.0.24002.92) - 13th Gen Intel(R) Core(TM) i5-13600K (20 Threads)

### Issue description

I'm creating a minecraft like game using cubes, See this video : https://www.youtube.com/watch?v=iQS3WelK7pU

And find the source code : https://pastebin.com/dtgJ8na8

I reliably get this error when I up the render_distance to around 18 - 24. The queue does not grow beyond 100, but the game crashes, and the only error supplied is:
USER ERROR: FATAL: Index p_index = 4294967294 is out of bounds (count = 32772). at: operator[] (./core/templates/local_vector.h:161)

I have no idea whats causing it. Any help is appreciated.

### Steps to reproduce

Up the chunks to beyond 18, crashes randomly.

### Minimal reproduction project (MRP)

Honestly I'm not sure what causes this. Sorry.
