Windows 10: 0xC1900101-0x40021 error when in-place upgrading Windows 10 v2004

Hello.


I am trying to do an in-place upgrade of my machine's installed OS: Microsoft Windows 10 v2004 compilation 19041.450, using the latest Windows setup media. I ran the setup process from inside windows, and I keep the option to search for updates on and select to keep my apps and files.


During setup, after the second boot and at about 85% of the applying updates process, it gets an error, it shuts down, and when rebooting on, the machine reverts back to the previous state.

This is the error message dialog I get when logging back-in to Windows:


0xC1900101-0x40021

The installation failed in the SECOND_BOOT phase with an error during SYSPREP_RESPECIALIZE operation


I don’t have any antivirus/firewall program installed besides the default windows ones.


I have tried everything I know to resolve this:

- Did a disk clean

- Did a full a System File Check for errors: Dism.exe /online /Cleanup-Image /StartComponentCleanup&sfc/scannow&Dism /Online /Cleanup-Image /RestoreHealth&sfc/scannow&pause
- Did a Check Disk for errors
- Uninstalled all OEM device drivers graphics, sound, etc... and let Windows Update to install its-own versions
- Did a clean boot and, from there, ran Setup again
- …

But the problem is always the same.

Can anyone please analyse the C:\WINDOWS.~BT\Sources\Panther\* & C:\WINDOWS.~BT\Sources\Rollback\* log files I send in the following OneDrive link, in order to discover what is preventing this update?

Thank you in advance.
