1. Make sure your fingerprint reader or camera hardware is not damaged and is properly connected to your computer.
If it is an external device, try to re-plug it and check if it is working properly.
2. Update the driver program:
Open “Device Manager”, locate the biometric device (e.g. fingerprint reader or webcam), check if there is a yellow warning flag, if so, right-click and select “Update Driver”.
3. Run Windows Update:
Make sure your Windows 11 Insider version is up to date. Sometimes system updates fix hardware compatibility issues.
4. Reset biometric data:
Open Settings > Accounts > Sign-in Options, scroll down to the Biometrics section. Try deleting and resetting your fingerprint or facial data.
5. Disable and re-enable biometrics:
In Settings > Accounts > Sign-in Options, turn off biometric sign-in, then restart your computer and turn it on again.
