Sorry I didn't answer earlier, i did not get the notification :/
Is it still broken and what browser are you using ?
It might be related to WebGL2 support, could you run this command in your browser's console ?

const gl = document.createElement('canvas').getContext('webgl2');
if (!gl) {
  console.log('your browser/OS/drivers do not support WebGL2');
} else {
  console.log('webgl2 works!');
}
