Please help where is the error

Answer 1

Use the_archive_title(); instead of single_cat_title(); and the_archive_description(); instead of category_description();

add this code to functions.php

add_filter('get_the_archive_title', function ($title) {
    return preg_replace('/^\w+: /', '', $title);
});
