wp_insert_user Not Working

Hi there guys, I’m trying to create a form is submited.
The code I used to test is this:

$userdata = array(
	'user_login' => 'login',
	'user_email' => '[email protected]',
	'user_pass' => wp_hash_password('123456'),
	'user_url' => 'https://none.com',
	'display_name' => 'John Doe',
	'description' => '',
	'role' => 'author'
);

$user_id = wp_insert_user( $userdata );

Nothing happened!

Tried with wp_create_user() and nothing happened too!
