Hi, Re-enrolling facial data may not resolve the issue due to underlying driver or camera service disruptions introduced during the update. As a temporary workaround, we recommend switching to PIN or password sign-in while we work on a fix. Ensuring the latest camera drivers are installed via Windows Update or the device manufacturer’s support site may also help restore functionality.
We’ll provide further guidance as soon as a resolution is available. If my answer is useful for you, please vote for it.
Best regards, Quinnie Quoc.
