WINBIO_E_LOCK_VIOLATION
WINBIO_E_LOCK_VIOLATION means the requested operation conflicts with an existing lock on the unit, session, or related data. The error protects the biometric pipeline from unsafe concurrent use.
What to check
- Identify the session that owns the lock and release it only after its operation completes.
- Avoid mixing enrollment, raw capture, and maintenance work on the same unit without clear ownership.
- After an abnormal client exit, verify that the service and driver released stale resources.
