Can you try replace this JavaScript. Hope this help you

function get_checkbox_value(){
    var array = [];
    jQuery(':checkbox:checked').each(function(i, _this){
      var checkboxname = jQuery(_this).attr('name'); checkboxname = checkboxname.replace('[]','');
      array[checkboxname]=[];
      array[checkboxname].push(jQuery(this).val());
    });    
    return array;
}

jQuery(document).ready(function(){

    jQuery("#filterForm").submit(function(e){
        e.preventDefault();

        var formdata = get_checkbox_value();
        var ajaxurl = "<?php bloginfo('url');?>/wp-admin/admin-ajax.php";

      jQuery.ajax({
          url: ajaxurl,
          type : 'POST',
          data: {
            'action':'all_give_aways_filter',
            'data' : formdata,
          },
          success : function( response ) {
              console.log(response);
          }
      });
  });
});
