### Godot version

v4.0.beta.custom_build [291add339]

### System information

Windows 10, Forward+, NVIDIA GeForce GTX 1050 Ti (31.0.15.1694)

### Issue description

I was testing if #69669 was solved by #70418, which it seemed to be. However, I got a wall of errors at the same time.

In the minimal reproduction project below in this Issue, I get errors when instantiating many of the same `GPUParticle2D` scene. In my earlier Godot 4 build (v4.0.beta.custom_build [2a04b18d3]) I did not get any errors (but got the occasional artifact as was my original issue in #69669).

I suspect the PR #70418 solved the artifact, but possibly introduced new bugs. However, I have not specifically built Godot with, and without the PR in question.

I believe this is the start and end of the errors - after which they repeat.

### Steps to reproduce

- Create a GPUParticle2D scene
- Instantiate the scene several times
- Observe the debugger get flooded with errors

### Minimal reproduction project

This project only instantiates default GPUParticle2D scenes with a default particle material.
