Hello, thanks for checking this out.

I tried to remove the comments by doing a regular expression search like the following in function.php, line 347

                    // Strip out gutenberg comments from mainEntityOfPage
                    $gutenberg_comments_pattern = '/<!--\s+(\/)?wp:[a-z\-]+(\s+(\{.*?\}))?\s+-->/';
                    $no_comments_webpage = preg_replace($gutenberg_comments_pattern, "", $webpage['@id']);

                    $output['mainEntityOfPage'] = $no_comments_webpage;

I tested the code elsewhere and it seemed to work, but not with the plugin. can you prove some sample output of $webpage['@id'] or provide some pointers? :)
