Custom tag broke with new update

Hello there,

I have the following code and with the new update the tag stopped working. I dont understand what is going on. Any help is appreciated.

add_action('wpcf7_init', 'custom_form_tag_qty');

function custom_form_tag_qty() {

    wpcf7_add_form_tag(array('qty'), 'custom_qty_form_tag_handler', true);

}

function custom_qty_generate_input_unique_name($init, $tab, $row, $field) {

    return $init . '____' . $tab . '____' . $row . '____' . $field;

}

function custom_qty_form_tag_handler($tag) {

    $tag = new WPCF7_FormTag($tag);

    $atts = array();

    $atts['id'] = $tag->get_id_option();

    $atts['name'] = $tag->name;

    $atts = wpcf7_format_atts($atts);

    $myCustomField = '

    <div class="row b2b__info-table-title">

        <div class="col-7">

            <div class="b2b__info-table-cell font-noto">' . $tag->raw_values[2] . '</div>

        </div>

        <div class="col-5">

            <div class="b2b__info-table-cell font-noto">'.__('Ποσότητα', 'theme-name').'</div>

        </div>

    </div>

    <div class="row b2b__info-table-data">

    ';

    foreach ($tag->raw_values as $key => $value) {

        if ($key > 2) {

            $myCustomField .= '

                <div class="col-7">

                    <div class="b2b__info-table-cell">' . $value . '</div>

                </div>

                <div class="col-5">

                    <div class="b2b__info-table-cell">

                        <div class="b2b__input-container">

                            <div class="b2b__input-minus">-</div>

                            <input type="number" class="b2b__input" value="0" name="' . custom_qty_generate_input_unique_name($tag->raw_values[0], $tag->raw_values[1], $tag->raw_values[2], $value) . '" min="0" max="999">

                            <div class="b2b__input-plus">+</div>

                        </div>

                    </div>

                </div>

            ';

        }

    }

    $myCustomField .= '</div>';

    return $myCustomField;
