STATUS_GRAPHICS_CANT_ACCESS_ACTIVE_VIDPN
STATUS_GRAPHICS_CANT_ACCESS_ACTIVE_VIDPN means the requested operation could not access the VidPN because that VidPN was active on the display adapter. An active VidPN is the configuration currently set on the adapter; changing it is governed by display-mode management rules rather than ordinary object access.
Preserve the active topology and separate read-only observation from an operation that would alter source, target, path, or mode-set state. A caller that needs to propose or validate a new configuration should use the supported display-management stage instead of treating the active object as freely mutable.
Evidence that matters
- The active source/target paths and any mode or topology request that preceded the failure.
- Whether the adapter was starting, stopping, switching GPUs, or processing a display configuration change.
- The exact DDI or management operation that attempted to access the active VidPN.
Retaining the active configuration at failure time is especially valuable because a later topology query may already reflect the next configuration and hide the condition that caused the rejection.
