What does HRESULT 0x80290215 (TBSIMP_E_NOTHING_TO_UNLOAD) mean?

TBSIMP_E_NOTHING_TO_UNLOAD

There is no live resource corresponding to the unload request

TBSIMP_E_NOTHING_TO_UNLOAD (0x80290215) means the cleanup path targets an object that has already been unloaded, expired, or was never successfully loaded in this context. It is primarily a lifetime-accounting issue.

Evidence to capture

Record resource/vhandle, owning context, load result, prior unload/flush calls, and error paths that may perform cleanup twice.

Focused correction

Make cleanup idempotent and unload only resources whose successful load is still owned by the context. Reacquiring a resource is unnecessary if the operation being performed is only cleanup.
