My old HP ProBook 4320s needed a working Windows 10 driver (4.4.234.00) for Hello.
This one works (install it manually): SP58869.exe from HP
Important note: If Windows installs an older driver before you do, the HP setup won’t replace it. So first uninstall the old one from the device manager (with the delete driver option) and install the INF manually
Now it should look like this!
