livequery is not working after WordPress 5.6 + update

Question

I am using livequery 1.3.6. When I updated WordPress 5.6+ version, it doesn't work. Can you help me to fix the issue. I am using in my javascript function like below code

$('#my-popup').livequery(function() {

    myFunc.load();

    $('#my-popup').closest('#TB_window').addClass('my-shortcodes-popup');

    $('.wp-color-picker-field').wpColorPicker({
        change: function(event, ui) {
            setTimeout(function() {
                myFunc.loadVals();
                myFunc.cLoadVals();
            }, 1);
        }
    });
});

I am using it for visual shortcodes generator

When we click on link from dropdown, it options popup with shortcode options

It was working perfect with WordPress 5.5 but after update with 5.6 + it doesn't detect livequery and click events inside livequery functions

I am using this livequery in below code

jQuery(document).ready(function($) {

  var myFunc = {
    loadVals: function() {
      var shortcode = $('#_my_shortcode').text(),
        uShortcode = shortcode;

      // fill in the gaps eg {{param}}
      $('.my-input').each(function() {
        var input = $(this),
          id = input.attr('id'),
          id = id.replace('my_', ''), // gets rid of the my_ prefix
          re = new RegExp("{{" + id + "}}", "g");
        var value = input.val();
        if (value == null) {
          value = '';
        }

        uShortcode = uShortcode.replace(re, input.val());
      });

      // adds the filled-in shortcode as hidden input
      $('#_my_ushortcode').remove();
      $('#my-sc-form-table').prepend('<div id="_my_ushortcode" class="hidden">' + uShortcode + '</div>');

    },
    cLoadVals: function() {
      var shortcode = $('#_my_cshortcode').text(),
        pShortcode = '';
      shortcodes = '';

      // fill in the gaps eg {{param}}
      $('.child-clone-row').each(function() {
        var row = $(this),

          re = new RegExp("{{" + id + "}}", "g");
          var value = input.val();
          if (value == null) {
            value = '';
          }
