New installation fatal error in 5.9.3 at edit or create entry

I just make a new download and installation of Wordpress. So far so good until I edit or create a new entry. Remove it works.

Notice: Undefined property: WP_REST_Terms_Controller::$sql_clauses in /wp-includes/rest-api/endpoints/class-wp-rest-terms-controller.php on line 625

I'm totally lost here. I didn't touch any code or database, just the installation. Any tip or help or comment will be preciated. No plugins. Just Vanilla.
