How to clone a gltf?

I see character in your path name, so it will most likely be a skeleton model… Try this approach:

import * as SkeletonUtils from 'three/addons/utils/SkeletonUtils.js';

//....

const CHARACTER_PATH = "https://threejs.org/examples/models/gltf/RobotExpressive/RobotExpressive.glb";
  let myGltf, myClone;

  function loadGLTF(url) {
  return new Promise((resolve, reject) => {
    new GLTFLoader().load(
      url,
      (gltf) => resolve(gltf),
      undefined,                                            
      (error) => reject(error)
    );
  });
}

loadGLTF(CHARACTER_PATH)
  .then((gltf) => {
    scene.add(gltf.scene);

    const clone = SkeletonUtils.clone(gltf.scene);
    gltf.scene.position.x = -2;
    gltf.scene.position.y = -2;
    clone.position.x = 2;
    clone.position.y = -2;
    scene.add(clone);
  })
  .catch((error) => {
    console.log(error);
  });
