Can’t assign menu parent id or menu item breaks

Update

Solution was easy I’m stupid I just tweaked the menu creation and directly assigned the parent-menu-id:

if (!empty($term->parent) && $term->parent != 0) {
            $parent_menu_item_id = get_parent_menu_item_id_by_name($term->parent, $menu_id);
            if ($parent_menu_item_id) {
                $menu_item_id = wp_update_nav_menu_item($menu_id, 0, array(
                    'menu-item-title' => $term_name,
                    'menu-item-object-id' => intval($term_id),
                    'menu-item-object' => 'product_cat',
                    'menu-item-type' => 'taxonomy',
                    'url' => get_term_link($term),
                    'menu-item-parent-id' => $parent_menu_item_id,
                    'menu-item-status' => 'publish'
                ));
            } else {
                $menu_item_id = wp_update_nav_menu_item($menu_id, 0, array(
                    'menu-item-title' => $term_name,
                    'menu-item-object-id' => intval($term_id),
                    'menu-item-object' => 'product_cat',
                    'menu-item-type' => 'taxonomy',
                    'url' => get_term_link($term),
                    'menu-item-status' => 'publish'
                ));
            }
        }
