Notebook Operating System and Recovery

I have 2 identical Spectre X360 laptops: Model = 15T-DF000,  Product = 4HG39AV_1

...First laptop is Win-10 as shipped by HP and all subsequent updates installed. No problems.

...Second laptop: Also shipped with win-10 but...

Yesterday, I used a DVD to do a fresh install Windows 11 that I downloaded from Microsoft, as a MSFT analysis said my Win-10 laptop is upgradable to the new OS. The problem I am having is that the Windows Hello Face (facial recognition for sign-in) is not working. I didn't try to install or use it when this laptop was running Windows 10, so I don't know about it. But Hello Face is working on my first identical Win-10 Spectre.

When I go into Settings -> Account -> Sign-in Options. The Facial Recognition option displays the text "This option is currently unavailable." The explanation was "We couldn't find a camera compatible with Windows Hello Face." So, I went to Settings - Apps -> Optional features. There I found in the list: Facial Recognition (Windows Hello). So I installed it & re-booted the laptop. When I went back to implement the Facial Recognition (Windows Hello) app, it still displayed the message "This option is currently unavailable." Same explanation: "We Couldn't find..."

I then launched SERVICES.MSC and started the service: Windows Biometric Services. Went back to activate the Hello Face, but still could not activate the Hello Face for the sign-in option.

In Device Manager, under Biometric Devices, I only have one item: Synaptics WBDI Fingerprint Reader - USB 102 (SGX). But on my Win-10 Spectre I have an additional device called Windows Hello Face Software Device.

When inspect the directory C:\Windows\System32\WinBioPlugIns on both laptops, the Win-10 Spectre has more DLL files in it and it also has a subdirectory called FaceDriver. My Win-11 Spectre is missing those files, even after going thru the process to install optional software.

Anybody have a clue as to how to implement the Windows Hello (Facial Recognition) software on my Win-11 Spectre?

Thanks for any and all advice.
