Windows 11 Update from 21H2 to 22H2 failed with 0x80070020 - 0x2000A ... SAFE_OS phase ... PREPARE_FIRST_BOOT operation

Hi All,
I have an issues when upgrading Windows 11 from 21H2 to 22H2 - and wanted to know if anyone else also had that experience.
I have setup Windows 11 with an unattended Setup file to move the Users Profile Directories to my second Drive. I used there almoste the same unattened.xml as I dir for Windows 10.
In my old Windows 10 Installation I did not had any issues with updates or upgrades in the last years.
Updates are working well in the Windows 11 installation, but as I wanted to upgrade to 22H2 I always got the error above.
From teh MS Community it was mentioned that this Error will come from the situation, that the User Profile Directory is not on the same Drive as the Windows installation.
As I got a lot of ideas from this (ans teh Win 10) forum, especially for unattended Installations I wanted to know if anybody has also this issue - and also probably a proper and long lasting solution.
In the MS Community they stated that I have to change the Reg back to the default and create a local Admin account to upgrade and after the upgrade I had to change back again.

Thanks for your help

Maverick
