BUG repport

I think I stumbled uppon a bug : When I create an object in blender with a material using a texture as metallic roughness, then export it as a GLTF+bin+texture, it imports well into godot 4.7 GUI, runs well on PC, on Quest 3 (deployed) but when deployed on a Pico 4 Ultra, the application initial loading never ends.

As soon as I remove the MetRough texture from the blender shader, (export-import again) then everything is fine.

It can easily be reproduced, but if needed, I can provide a simple gltf file (+bin+tex)
