Windows 10 20H2 .appx UI language pack problem

Hello

I want to provide 20H2 for our company. I use the same scripts as for 1909 to edit the image. What has changed are the language packages - .cab --> appx. Now I have the problem that at the first login the language is set to English, although everything should be in DE. After a few reboots and rebuilding the Windows index, everything is in DE. Does anyone know this problem? I would be very grateful for a tip.

What was done?

DISM was used to edit the image:

Dism /image:"$MntPath" /Set-AllIntl:de-DE
Dism /image:"$MntPath" /Set-UILang:de-DE
Dism /Image:"$MntPath" /Set-SysUILang:de-DE
Dism /image:"$MntPath" /Gen-Langini /Distribution:"$WimPath"
Add-WindowsPackage –Path "$MntPath" –PackagePath "$UpdPath" -LogLevel "1"
Dism /Image:"$MntPath" /Add-ProvisionedAppxPackage /PackagePath="$LngPath\$LPName" /licensepath="$LngPath\$LPLicence" /LogPath:"$LogPath\Dismlog-LANG.log"


After installation via Ivanti DSM first login:

Login screen is English
Settings partly in English:





lang.ini:
[Available UI Languages]
de-DE = 2
en-US = 3

[Fallback Languages]
en-US = en-us

What I found out is that there is a task scheduler:


But I want the language to be German at the first login and not wait. In addition, the index is still in English.

Does anyone have any ideas?

Thanks a lot!

I was able to solve the problem by finding the .cab files for 20H2:
