Can you provide a sample? From your description even a blender 3.5 gltf default cube will fail. If I remember correctly a empty scene will fail to import into godot engine regardless of version.

Godot has no way to import Blender shaders (our PBR differs from Blender's PBR enough that 1:1 translation isn't possible). Also Godot uses a different channel for normal maps than Blender.
