and we can make some changes to above-mentioned function:

function na_parse_request( $query ) {

if ( ! $query->is_main_query() || 2 != count( $query->query ) || ! isset( $query->query['page'] ) ) {
    return;
}

if ( ! empty( $query->query['name'] ) ) {
    $query->set( 'post_type', array( 'post', 'events', 'page' ) );
}
}

to:

function na_parse_request( $query ) {

if ( ! $query->is_main_query() || 2 != count( $query->query ) || ! isset( $query->query['page'] ) ) {
    return;
}
    
if ( ! empty( $query->query['name'] ) ) {
    
    global $wpdb;
    $pt = $wpdb->get_var(
        "SELECT post_type FROM `{$wpdb->posts}` " .
        "WHERE post_name = '{$query->query['name']}'"
    );
    $query->set( 'post_type', $pt );
}
}

in order to set right post_type value.
