I was wrong, in your loop you need to check if it’s the current post, if it is you set the term and if it’s not you clear the term, like you’re doing. Since you’re using a radio field it does not get set automatically. You also need to declare the global $post, and you need to do wp_reset_postdata after your loop. something like this.

<?php 

  function my_acf_save_post($post_id) {
    global $post;
    // get the value of the radio button that is selected
    $value = get_field('is_featured_video');
  
    // only run the code, if the user has selected "Yes" (yes_featured_video)
    if($value == 'yes_featured_video') {
      // start by fetching the terms for the featured_video taxonomy (there is only one, which is 'yes')
      $terms = get_terms( 'featured_video' );
  
      if(!empty($terms)) {
        // now run a query for each term
          foreach ( $terms as $term ) {
              $args = array(
              'post_type' => 'asc_video',
              'featured_video' => $term->slug
          );
          $query = new WP_Query( $args );
          }
  
        // start the loop
        while ( $query->have_posts() ) : $query->the_post();
          // remove the slug from the video that previously had the 'yes' slug assigned to it
          if ($post_id != $post->ID) {
            wp_set_object_terms( get_the_ID(), '', 'featured_video');
          // set the radio button value to "No" (no_featured video)
            update_field('is_featured_video', 'no_featured_video');
          } else {
            wp_set_object_terms($post_id, $term, $term->taxonomy);
          }
        endwhile; 
        wp_reset_postdata();
      }
  
      // assign the 'yes' slug to the post
      wp_set_object_terms($post_id, 'yes', 'featured_video');
      
    }
  
     
  
  }
  
  add_action('acf/save_post', 'my_acf_save_post');
