Hello
I had similar issues twice within 3 months. I could not find Biometric Devices under the Device Manager at all.
I am using Dell's Inspiron 16 5620 laptop with Windows 11 Home. Later I contacted Dell Support, did a hardware diagnostic test, and checked for new updates under "Drivers & Downloads". Checked for "Fingerprint Sensor Driver" under "Drivers & downloads" and installed it.
Once installed successfully, I was able to see Biometrics Devices in Device Manager (if you are not able to see biometric devices there, then you have to download the driver manually first as I did). Then I restarted the system and the fingerprint started working again. I have also added a new fingerprint along with my old one.
This issue is repeated whenever Windows updates are happening in our system. For the last few months, I didn't have any Dell-related updates but did a couple of Windows updates.
You guys can get the "Goodix MOC fingerprint" driver from Dell's official support website(if you are a Dell user). Likewise, other brand users can find their brand-specific fingerprint driver from official websites.
I'm not 100% sure this will work for everyone. But thought of adding it here since it worked for me!
