How can I get archives for specific category without category_base in the url?

I’m using this code to get archives for a specific category:

function extend_date_archives_add_rewrite_rules($wp_rewrite){
    $rules = array();
    $structures = array(
        $wp_rewrite->get_category_permastruct() . $wp_rewrite->get_date_permastruct(),
        $wp_rewrite->get_category_permastruct() . $wp_rewrite->get_month_permastruct(),
        $wp_rewrite->get_category_permastruct() . $wp_rewrite->get_year_permastruct(),
    );
    foreach( $structures as $s ){
        $rules += $wp_rewrite->generate_rewrite_rules($s);
    }
    $wp_rewrite->rules = $rules + $wp_rewrite->rules;
}
add_action('generate_rewrite_rules', 'extend_date_archives_add_rewrite_rules');

It works fine and I get an URL like:
example.com/category_base/category_name/date/YYYY/MM

The problem is that I would like to have an URL without the category_base: example.com/category_name/date/YYYY/MM

If I use a plugin to delete de “category_base” (like WP no category base) or simply I use “str_replace” to delete the “category_base”, I get a 404 error page in all pages and single pages.

What can I do?

Thanks.

Added notes:

If I use:

function extend_date_archives_flush_rewrite_rules(){
    global $wp_rewrite;
    $wp_rewrite->flush_rules();
}
add_action('init', 'extend_date_archives_flush_rewrite_rules');
function extend_date_archives_add_rewrite_rules($wp_rewrite){
    $rules = array();
    $structures = array(
        $wp_rewrite->get_category_permastruct() . $wp_rewrite->get_date_permastruct(),
        $wp_rewrite->get_category_permastruct() . $wp_rewrite->get_month_permastruct(),
        $wp_rewrite->get_category_permastruct() . $wp_rewrite->get_year_permastruct(),
    );
    foreach( $structures as $s ){
        $rules += $wp_rewrite->generate_rewrite_rules($s);
    }
    $wp_rewrite->rules = $rules + $wp_rewrite->rules;
}
add_action('generate_rewrite_rules', 'extend_date_archives_add_rewrite_rules');

example.com/category_name/YYYY works fine, but single and pages go to 404 page. But If I only use:

function extend_date_archives_add_rewrite_rules($wp_rewrite){
        $rules = array();
        $structures = array(
            $wp_rewrite->get_category_permastruct() . $wp_rewrite->get_date_permastruct(),
            $wp_rewrite->get_category_permastruct() . $wp_rewrite->get_month_permastruct(),
            $wp_rewrite->get_category_permastruct() . $wp_rewrite->get_year_permastruct(),
        );
        foreach( $structures as $s ){
            $rules += $wp_rewrite->generate_rewrite_rules($s);
        }
        $wp_rewrite->rules = $rules + $wp_rewrite->rules;
    }
    add_action('generate_rewrite_rules', 'extend_date_archives_add_rewrite_rules');

Then all single and pages work fine, but example.com/category_name/YYYY goes to 404.
Any idea? I refresh permalinks, and I continue with the problem 🙁
