ERROR_GRAPHICS_OPM_INVALID_INFORMATION_REQUEST

The status-query message failed session validation

This error applies to GetInformation and COPP-compatible status queries. OPM does not treat a status request as an ordinary read: the request carries a fresh random number, a status sequence number, parameters for the requested information, and an OMAC calculated over the authenticated portion of the structure.

Most cases are state-management defects in the caller: using the command counter for a status request, incrementing the counter at the wrong time, reusing a request after an output was recreated, signing a different byte range than the driver expects, or passing a structure-size and request-GUID combination that does not agree.
