[Closed] AI not loading, language mapping not possible

Background of the issue:
I have WPML installed and would like to use the AI features. Unfortunately, the AI section doesn’t load. In the settings, I get a message about mapping my default language, German, to a supported language for automatic translation. When I click the 'Map language' button, there’s no option available, and the column for Language Mapping isn’t displayed.

Symptoms:
The AI section doesn’t load. The settings display a message: 'Your default language, German, must be mapped to a supported language to use automatic translation.' The 'Map language' button shows no options, and the Language Mapping column isn’t displayed.

Questions:
Why is the AI section not loading?
How can I map my default language, German, to a supported language?
Why are there no options available when I click the 'Map language' button?
Why is the Language Mapping column not displayed?
