You may need to use setup_postdata() and wp_reset_postdata() along with the global $post variable described here https://www.advancedcustomfields.com/resources/post-object/

add_action('acf/save_post', 'copy_persons_to_people', 20); // priority 20 runs after acf has saved content
function copy_persons_to_people($post_id) {
  // we need to create a new meta key to hold the list of people
  // this is the meta key you'll use to set up the search of this field
  $meta_key = 'related_peoples';
  // clear this field if it exists for this post
  // need to start fresh each time
  delete_post_meta($post_id, $meta_key);
  // see if there are any related people
  $persons = get_field('team_members');
  if ($persons) {
    global $post;
    foreach ($persons as $post) { // need to use $post here
      setup_postdata($post);
      add_post_meta($post_id, $meta_key, $post->post_title, false);
    }
    wp_reset_postdata();
  }
}
