With php 8.2 there are some deprecated errors

Hi, with php 8.2 there are some deprecated errors
PHP Deprecated: preg_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated in /wp-includes/kses.php on line 1807
Here is the quick fix:
in render.php line 135 change this line
echo wp_kses_post( block_template_part( $menu_slug ) );
ti this
echo wp_kses_post( (string) block_template_part( $menu_slug ) );
and error diasappears
