Please switch wp-db.php for class-wpdb.php

Hi, I have following deprecation notice in my log:
Deprecated: File wp-db.php is <strong>deprecated</strong> since version 6.1.0! Use wp-includes/class-wpdb.php instead. in /wp-includes/functions.php on line 5573

I suppose it is thrown due to following line in wse_functions.php:
require_once(ABSPATH.'wp-includes/wp-db.php');
