Answer
Clean and uncover the TrueDepth camera, check Face ID settings, restart and reset Face ID, then seek service if the camera reports a hardware problem.
Clear the TrueDepth view
Remove anything covering the top camera area, clean it gently, and hold the iPhone at a supported distance and orientation.
Check enabled uses
Open Settings > Face ID & Passcode and enable Face ID for the task that is failing.
Restart and reset
Restart, update iOS, then choose Reset Face ID and enroll again if the camera can complete setup.
