This thread is resolved. Here is a description of the problem and solution.
Problem:
You are unable to add the language switcher to a menu either through WPML settings or by manually adding the block element.
Solution:
We recommend adding the language switcher directly to the template. You can find detailed instructions on how to do this here: https://wpml.org/documentation/getting-started-guide/language-setup/language-switcher-options/#add-language-switcher-template
Additionally, to identify if there is a conflict causing this issue, please follow these steps:
1. Temporarily disable all plugins except for WPML.
2. Switch to a default theme, such as Twenty Twenty-Five.
3. Check if the issue still occurs.
If these steps do not resolve the problem, the solution might be outdated or not applicable to your specific case. We highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the issue persists, please open a new support ticket at WPML support forum for further assistance.
