After some hacking, I can actually confirm that replacing inputs:file.connect with inputs:file can solve the texture issue. We will workaround like this for now. But wondering whether there is a long term path to support inputs:file.connect? After all, it works for visionOS 1 :)

you mean use: asset inputs:file = @direct-0041023a-226c-4b6b-80f3-c6e855fd88c0-mesh_albedo.png@ instead of asset inputs:file.connect = </_041023a_226c_4b6b_80f3_c6e855fd88c0_mesh/Materials/defaultMat_.inputs:diffuseColor> ? Is that inputs:file.connect being the problematic part?
