Look how it works at my test site – demo video.

Slightly enhanced code version. Update your copy:

add_filter('ure_edit_posts_access_id_list', 'ure_edit_posts_access_set_id_list');

function ure_edit_posts_access_set_id_list($list) {
    if (!current_user_can('edit_others_pages')) {
        return $list;
    }
    
    $slugs = array('shop', 'busket');   // input blocked pages slug here
    $id_list = array();
    foreach($slugs as $slug) {
        $page = get_page_by_path($slug);
        if (!empty($page)) {
            $id_list[] = $page->ID;
        }
    }
    if (count($id_list)>0) {
        $id_list_str = implode(',', $id_list);
        $list .= $id_list_str;
    }

    return $list;
}

add_filter('ure_edit_posts_access_restriction_type', 'ure_edit_posts_access_set_restriction_type');

function ure_edit_posts_access_set_restriction_type($restriction_type) {
    if (current_user_can('edit_others_pages')) {
        $restriction_type = 2; // Block
    }
    
    return $restriction_type;
}
