"Uniforms were never supplied for set (3) at the time of drawing, which are required by the pipeline" after freeing a GPUParticle2D

Godot version

4.1.1.stable.mono

System information

Godot v4.1.1.stable.mono - macOS 13.6.0 - Vulkan (Forward+) - integrated Apple M1 - Apple M1 (8 Threads)

Issue description

I have a Node2D which is responsible for emitting 2 children (GPUParticles2D).

I also added the timer to the parent node and connected its Timeout signal to free the parent.

The error I get is:

E 0:00:07:0555   compute_list_dispatch: Uniforms were never supplied for set (3) at the time of drawing, which are required by the pipeline
  <C++ Error>    Method/function failed.
  <C++ Source>   drivers/vulkan/rendering_device_vulkan.cpp:8026 @ compute_list_dispatch()

I remember having this problem around 6 months ago and don't remember finding an adequate solution. What fixed it back then was changing the GPUParticle2D node type to CPUParticle2D.

Steps to reproduce

• Create a scene and add Node2D to it

• Add a few GPUParticle2D children (duplicate one a few times favorably)

• Add a timer child

• Add a script to the parent node

• Set the timer WaitTime to the particles' LifeTime

• In the _Ready() method, add the listener to the Timeout signal of a timer, which frees the node

• In the _Ready() method, emit the particles

I can't seem to reproduce this, but the instructions seem a bit vague.

Could you attach a MRP test project? It will give a common base to all testers to see if this only happens on specific systems for example. There is also a good chanche that this is a duplicate of #82257 as mentioned, but testing this to make sure would still be useful.
