On your phone’s chrome browser open [https://codepen.io/optimus007-the-looper/pen/QWMwKbB](https://codepen.io/optimus007-the-looper/pen/QWMwKbB)

using the start AR button will not load the glb , session crashes but there’s no error

using the example ar button it loads the glb models hosted on github’s three js/models/gltf/

what could be causing the crash ?
