Comment:

 I agree with both @Mamaduka and @swissspidy.

 Doing a search of where the `wp_render_duotone_filter_preset()` function
 is declared:

 * In WP 5.9.1: it's `function` only appears in one place, i.e. in the `wp-
 includes/deprecated.php` file.
 * In Gutenberg plugin: it does not exist.

 The issue then is not in 5.9.1 or Gutenberg. Rather, the issue is an
 incomplete upgrade to 5.9.1.

 @etilley I'd suggest reinstalling 5.9.1 to ensure all new files are
 present. Why? Since there's an incomplete installation of the duotone
 file, it's probable other files may not have been updated too.
