Paginate_Links page 2 doesn’t work

I believe the mistake is using get_query_var( 'paged' ): this comes from the main query, not from your custom query. Try this (untested):

$current_page = 1;

if ( isset( $_GET['page'] ) ) {
    $current_page = absint( $_GET['page'] );
}

And then replace uses of get_query_var( 'paged' ) with $current_page.
