This thread is resolved. Here is a description of the problem and solution.

Problem:
If you're experiencing issues where enabling the language switcher causes some links to stop working and affects the dropdown theme of the page menu sections, it might be due to the menu configuration in your secondary language not matching the primary language.
Solution:
We recommend following these steps to resolve the issue:
1. Go to Appearance → Menus
2. Switch to the menu of the secondary language
3. Apply the same Mega Menu options/configuration as you have in the main (original) menu
4. Save the menu

Thank you for contacting WPML support.

I have checked your website, but haven't noticed the issue. Could you please upload a screenshot showing the problem?

How did you add the language switcher?

Please check both languages ​​of the page - when clicking on the home sections, the menu does not load.
As you can see in the screenshot, when you click on the black menu on the first page, an error appears.

Inspecting the menu on the translated page, I did not see the submenu render on page load. If you disable the language switcher, does the issue disappear? If so, try adding the language switcher again from WPML → Languages → Menu language switcher as a test.

Have you attempted to synchronize the menu via WPML → WP Menus Sync?

yes, that's the problem. when i disable the switcher, the page works, but only in one language - english.adding the language switcher again from WPML → Languages → Menu language switcher as a test - i cann't find this option.
Have you attempted to synchronize the menu via WPML → WP Menus Sync? - Yes.

Please find attached some screen from the WPML Languages settings, Can you help me understand if everything is correct?

Thank you.

Thank you for the clarification.

Just to make sure we’re addressing the correct issue, could you please confirm what exactly happens?

Are you referring to:
1. The menu dropdown not working on the secondary language when the language switcher is enabled?

or
2. A 404 error on the product category page in the secondary language?

These are two different issues with different causes, so your confirmation will help me guide you properly.

Let me know which one you’re experiencing.
