TPM_E_KEY_ALREADY_FINALIZED

TPM_E_KEY_ALREADY_FINALIZED means an application attempted to finalize a TPM-backed key that has already completed its creation lifecycle.

Treat this as an application state-management issue: reuse the finalized key or create a new key only when the workflow requires it.
Do not rerun finalization after reconnecting to an existing key handle.
Record key lifecycle state outside transient process memory when a provisioning workflow may be resumed after restart.
