I couldn't figure out the best area label to add to this issue. Please help me learn by adding exactly one area label.

As mentioned in the above bug there is an issue at:

runtime/src/coreclr/src/vm/interopconverter.cpp

Lines 465 to 473 in a4c050e

	if (TryGetComIPFromObjectRefUsingComWrappers(*poref, &pUnk))
	{
	SafeComHolder<IUnknown> pvObj;
	hr = pUnk->QueryInterface(iid, &pvObj);
	if (FAILED(hr))
	COMPlusThrowHR(hr);
	RETURN pUnk;
	}

There is also another instance of the same issue lurking higher in the file:

runtime/src/coreclr/src/vm/interopconverter.cpp

Lines 176 to 198 in a4c050e

	if (TryGetComIPFromObjectRefUsingComWrappers(*poref, &pUnk))
	{
	hr = S_OK;
	SafeComHolder<IUnknown> pvObj;
	if (ReqIpType & ComIpType_Dispatch)
	{
	hr = pUnk->QueryInterface(IID_IDispatch, &pvObj);
	}
	else if (ReqIpType & ComIpType_Inspectable)
	{
	SafeComHolder<IInspectable> pvObj;
	hr = pUnk->QueryInterface(IID_IInspectable, &pvObj);
	}
	if (FAILED(hr))
	COMPlusThrowHR(hr);
	if (pFetchedIpType != NULL)
	*pFetchedIpType = ReqIpType;
	RETURN pUnk;
	}
