ERROR_GRAPHICS_OPM_SESSION_TYPE_CHANGE_IN_PROGRESS

The session transition is not a stable OPM state

OPM depends on the kind of Windows session and the desktop that owns the video output. During a transition between console, disconnected, or remote session states, the output contract is intentionally unstable. The error is not evidence that a particular OPM command or HDCP capability is invalid.

During this interval, issuing more status or configuration requests against the same object can mix a state transition with a protocol failure. The correct boundary is the session event: pause protected playback handling, observe the resulting display topology, and create a new output session only after the environment has settled.

What to avoid

  • Do not advance or reset OPM counters merely because the session change is still in progress; a replacement OPM object requires a fresh initialization exchange.
  • Do not classify a remote-session transition as an HDCP handshake problem.
  • If the session change removes the output, handle the later destroyed-output or renegotiation condition rather than preserving the old interface.
