I have an HP All-in-One 27-a275na.
All was working well under Win11 23H2 and just downloaded the ISO for Win11 24H2. Kept only my data to get the benefit of having the best possible install and then reinstalled only the latest versions of the apps I wanted.
Have checked for corrupted files (none found), deleted the Facial Recognition (Windows Hello) Software Device in Device Manager & Rebooted.
On restart the machine fails to start camera and asks for PIN and then when I try to setup Windows Hello Facial Recognition I get the Error Message " Sorry, something went wrong. Couldn't turn on Camera. Make sure it's working properly.
On checking the camera app it all appears to be working properly, and the windows settings allow apps to contact it!

24H2 broke my Windows hello (PIN and facial) and security key (Yubico YubiKey 5C NFC) Windows sign-in as well. Only rolling back to 23H2 allowed Windows Hello/Security Key sign in to work again. Appears to be a bug with 24H2. At least 2 other users in our org reported the exact same issue. Windows Hello and security key worked for all application sign-ins, they just broke for Windows sign-in under 24H2.
I looked into this last month. Windows 24H2 (Oct 9 Update, UBR: 2033) does not include a codec or method for using certain Windows Hello Cameras with the Biometrics Framework App. This could also be caused by an unsupported preview resolution or color encoding used by the app.
This applies to enrollment. If you upgrade from a previous version of Windows and facial data is preserved, then Windows Hello Facial Recognition will continue to work. However, removing/re-enrolling will break until Microsoft fixes the issue.
I suspect newer cameras that support Enhanced Sign-in Security are working.
The error eventually translates to, "No suitable transform was found to encode or decode the content."
Run > Winver will tell you Windows version number.

Any Instructions anywhere on how to downgrade?
Open the Settings App, then got to System - Recovery, is there an option there to roll back to 23H2 to see if that gets Facial Recognition working again until they iron out the problems in 24H2?
Hi, I am Dave, I will help you with this.
The webcam drivers used for the Photos app are different from the drivers for the Infrared functionality required for Windows Hello, below is the support page for your PC on the HP website, from the Driver-Enabling section, donwlaod and re-install the version of IR webcam drivers they provide.
