Background of the issue:
I'm trying to add the HTML sitemap feature of RankMath (hidden link). Once the feature was enabled, a shortcode was given to add to the page I wanted to display the HTML sitemap. The English page works fine (hidden link). The Thai page (hidden link) throws a fatal error.

Symptoms:
The Thai page throws a fatal error: [06-Jun-2024, 05:20:27 UTC] PHP Fatal error: Uncaught TypeError: Cannot access offset of type string on string in /var/www/htdocs/wp-content/plugins/wp-seo-multilingual/classes/RankMathSEO/Sitemap/Hooks.php:69

Questions:
Why does the Thai page throw a fatal error when using the RankMath HTML sitemap feature?
How can I resolve the fatal error on the Thai page?
