This is a bug in windows as Use-WindowsUnattend freezes the process in Windows 11 (at least in my Win11 Microsoft corporate image).
Our build process is broken Vladimír (@machv) - is there a fix in build process so we can publish fixed version?
In new version you can use Unattend="DjoinCred" and it will not freeze. You can build new version manually with build.ps1 script once you download mslab files...
