I will add more accurate information.
Added custom preview button with reference to https://rudrastyh.com/wordpress/fullscreen-preview-button.html. Custom preview buttons worked without problem until ver 5.6.
When updating to version 5.7, clicking the button will reload the page.
How can I solve it?

// functions.php
add_action('acf/input/admin_enqueue_scripts', 'my_enqueue_scripts');
function my_enqueue_scripts()
{
  global $pagenow;

  if ( 'post-new.php' == $pagenow || 'post.php' == $pagenow ) {
    wp_enqueue_script('custom-preview', get_template_directory_uri() . '/js/custom-preview.js');
  }
}

// custom-preview.js
(function($) {
  acf.addAction('load_field/type=flexible_content', function() {
    $(document).on('click', '#custom-preview', function(e) {
      e.preventDefault();
      $('#post-preview').click();
    });
  });
})(jQuery);
