STATUS_FWP_TXN_IN_PROGRESS

The call belongs outside the explicit policy transaction

STATUS_FWP_TXN_IN_PROGRESS is the inverse of STATUS_FWP_NO_TXN_IN_PROGRESS: the operation must not be executed while the session has an explicit transaction open. It does not mean that transactions are generally broken.

Identify the failing API before changing transaction scope. For example, FwpmEngineSetOption0 changes engine settings and is documented to reject calls inside a transaction. Complete or abort the policy transaction first, then make the engine-setting change as a separate, traceable operation.

Diagnostic sequence

Log the API name, engine handle, transaction mode, and caller stack.
Find the matching FwpmTransactionBegin0 and determine why it remains open.
Commit or abort only after evaluating the already queued policy changes.
Run the prohibited operation outside the transaction, rather than silently moving unrelated filter updates.
