OOBE not run after sysprep, only a login screen is displayed

sysprepwindows 10

I try to prepare a Windows 10 21H1 installation with sysprep for imaging. I activated OOBE and generalize. Sysprep says that it was successful, but it ran to quick and the log file (setupact.log) ends abrubtly, see below.

The problem is that after a reboot I'm not presented with the OOBE first run setup stuff but just with the login screen for "other user" and I can't login there.

The panther directory has an empty setuperr.log and setupact.log contains two warnings, no errors and a lot of entries like this at the end:

...
2021-08-12 10:07:51, Warning                      TapiSysPrep.dll:RetainTapiLocations:RegQueryValueEx() returned 2
...
2021-08-12 10:08:15, Warning               SYSPRP SPPNP: Failed to configure oem31.inf (fn.inf). Err = 0x430
...

Since the warning is about a driver, investigate the driver store with dism /Online /Get-Drivers

Search for oem31.inf and/or fn.inf and try to uninstall that device before sysprep.

If confirmed it is the driver that is the culprit, the fun with trying to understand why starts. (But maybe that is a non issue if the driver just reinstalls after first login)
