Importing the below .glb or trying to open it in Rhino fails silently.
test_webp.glb (4.0 MB)
Looking at the extensions used, it has EXT_texture_webp.
For testing that this is the issue, repackaging it here https://gltf.report/ with textures in .png instead textureCompress({ targetFormat: 'png', resize: [1024, 1024] }), makes it open fine in Rhino.
