Yes. There are a lot of thread about that in the forum.
Start here: https://www.ntlite.com/community/index.php?threads/windows-11-pro-multi-language.5496/
Please explain yor problem as much as possible. What do you do, what`s your problem?
Thank you for your explanation that decribned all of the process and problems.The import works but the autounattend must also work the languages
AutoUnattend.xml doesnt "need to work" with the language packs, it needs to either have one or more of the languages available in the ISO or none at all.
What is the exact problem/error message?
If the languages doesnt show up in Settings > Languages, you need to add some registry keys to every edition in install.wim, its a known "feature" that Windows wont display languages not selected during Setup. Look into "block cleanup of unused preinstalled langpacks"

There is NO real information about what you are doing, what your goal is, what the problem is, what you are missing in the setup or in the installation. Please discribe your problem exactly (with more than one short sentence). Otherwise i`ll quit this thread.
Where do you miss the languages? In the setup or later in the installed windows? Please, please describe exactly your problem.
How did you integrate the languages? Please attach the preset-file.
Are these languages that you added ? Because there are already different languages in the setup (screen taken from the internet)

And you integrated the languages into boot.wim ?

Imported them via update into boot.wim or/and install.wim ?I downloaded the languages cab files and then imported them via update
You have set the languages in your XML. So these settings will be skipped during setup, that`s a normal behaviour.
If you integrate different languages in the install.wim you must leave these settings empty to have a choice in the setup.
