It is generally recommended to explicitly declare the visibility for methods.

    {
        $this->list_searcheable_acf = array("title", "sub_title", "excerpt_short", "excerpt_long", "xyz", "myACF");

The property list_searcheable_acf does not exist. Did you maybe forget to declare it?

        if (!class_exists('acf')) {
            add_filter('posts_search', [$this, 'advanced_custom_search'], 500, 2);
        }
    }

     *
     * @param $where
     * @param $wp_query
     * @return string
     */
    public function advanced_custom_search($where, &$wp_query)
    {
        global $wpdb;

        if (empty($where)) {
            return $where;
        }

        // get search expression
        $terms = $wp_query->query_vars['s'];

        // explode search expression to get search terms
        $exploded = explode(' ', $terms);

        if ($exploded === false || count($exploded) == 0) {
            $exploded = array(0 => $terms);
        }

        // reset search in order to rebuilt it as we whish
        $where = '';

        // get searcheable_acf, a list of advanced custom fields you want to search content in
        $list_searcheable_acf = $this->list_searcheable_acf;

        foreach ($exploded as $tag) {

$acf is not used, you could remove the assignment.
