Strip all HTML tags from user profile description field

functions.php

/**
 * Strip all HTML tags from user profile description field.
 *
 * @param int $user_id
 *
 * @return void
 */
function childtheme_strip_html_from_user_profile_description( $user_id ) {
	if ( ! isset( $_POST['description'] ) ) {
		return;
	}

	$user_id = wp_update_user( array(
		'ID' => $user_id,
		'description' => wp_strip_all_tags( $_POST['description'] ),
	) );
}
add_action( 'personal_options_update', 'childtheme_strip_html_from_user_profile_description', 13, 1 );

This would disable ALL html.

// disallow all HTML tags
add_filter( 'pre_user_description', 'wp_filter_nohtml_kses' );

Hi there,
Both solutions aren't working in my case, any there any workarounds please?
