custom fields content is not saving after update WordPress 6.1

I’m using meta-box creating a php file below is a sample of my code for custom fields for pages but I also use meta-box for custom post-type

<?php

add_action( 'add_meta_boxes', 'add_common_meta_box' );

function add_common_meta_box() {
  global $post;
  add_meta_box( 'common_id', 'Pages Custom Meta Box', 'common_meta_box_callback', 'page', 'normal', 'high' );
}

function common_meta_box_callback() {
  global $post;
  echo '<input type="hidden" name="common_noncename" id="common_noncename" value="' . wp_create_nonce( plugin_basename( __FILE__ ) ) . '" />';
  $single_image = get_post_meta( $post->ID, 'single_image', true );
  $header_slider = get_post_meta( $post->ID, 'header_slider', true );
  $content_single_image = get_post_meta( $post->ID, 'content_single_image', true );
  $maincontent_title = get_post_meta( $post->ID, 'maincontent_title', true );
  $pagebuttontext = get_post_meta( $post->ID, 'pagebuttontext', true );
  $pagebuttonurl = get_post_meta( $post->ID, 'pagebuttonurl', true );
  $pagebuttonurltitle = get_post_meta( $post->ID, 'pagebuttonurltitle', true );
  ?>
  <div class="cc-wrapper clear">

      add_post_meta( $post->ID, $key, $value );
    }
    if( !$value ) delete_post_meta( $post->ID, $key );
  }

}

thanks @threadi for the answer, but not sure where to I change the lines I don’t have that lines on my meta-box PHP file, is this in a specific place or file that I need to make the update?

thanks @threadi it works…
