The drupal_menu() doesn't apply the correct context cache to work in multilingual sites.
The Main menu content is cached on the first language a user loads it in and is never invalidated when the language context changes. This is because drupal_menu function renders the menu as a render array rather than as a traditional Drupal block, when doing so it doesn't add the correct cache contexts to the build's contexts.
In Drupal 10.x
admin/config/regional/language and add a new language ex. Spanishadmin/structure/types/manage/page and enable translation for Basic Page content typeadmin/config/regional/content-language and enable translations for Custom menu linkpage.html.twig file and add {{ drupal_menu('main') }} admin/config/regional/language/detection and enable Content language detection and select URLFurther testing:
Clear cache, and go to see the Spanish page first and then the English page, the Main menu content remains in Spanish
Add the languages:language_content tag to the cache context array.

Is this related to https://www.drupal.org/project/twig_tweak/issues/3427835 ✨ Add possibility to placeholder menu renders Active ?
It seems this may be unrelated to the previous issue. I will roll this patch in to a merge request so it's easier to review and test in the gitlab pipelines.
