Import errors with GLTF files and KHR_materials_specular

Godot Version 4.3 Stable.

I am trying to import a GLTF file into the engine so I can use it as a scene. I am trying to make a custom application to allow users to visualize their custom automated machines in AR. However, I keep getting errors while importing the file type.

Here are the errors I am getting.

Has anyone else ran into this issue/know how to fix it?

This is a known issue:

I suggest testing the pull request that implements it and reporting back if it works correctly.

On GitHub, it says the artifacts are expired and can no longer be downloaded. How do I proceed from there?

I also tried to use the nightly.link method as well and that also did not work. Any other ideas?
