Hello,

Please add the below code to the functions.php file in your child theme.

 if ( ! function_exists( 'xts_register_scripts' ) ) {
	/**
	 * Register scripts.
	 *
	 * @since 1.0.0
	 */
	function xts_register_scripts() {
		$config   = xts_get_js_scripts();
		$minified = xts_get_opt( 'minified_js' ) ? '.min' : '';

		if ( xts_is_combined_needed( 'scripts_combined_js' ) ) {
			return;
		}

		foreach ( $config as $key => $scripts ) {
			foreach ( $scripts as $script ) {
				$src = XTS_THEME_URL . $script['file'] . $minified . '.js';

				if ( 'scripts' !== $script['name'] ) {
					wp_register_script( 'xts-' . $script['name'], $src, array( 'xts-scripts' ), XTS_VERSION, $script['in_footer'] );
				} else {
					wp_register_script( 'xts-' . $script['name'], $src, array(), XTS_VERSION, $script['in_footer'] );
				}
			}
		}
	}

	add_action( 'wp_enqueue_scripts', 'xts_register_scripts', 20 );
}

Then clear the cache and check the issue again.

Kind Regards
