D7BB9305-5804-4F92-9CFE-119F4CB0563B 패키지를 로딩하다 오류가 발생한 것 같은데, 딱히 그게 어떤 패키지인지 레지스트리를 검색해 봐도 안 나옵니다. 문제를 좀 더 쉽게 파악하기 위해 저 오류 메시지의 창이 뜨는 시점에 devenv.exe에 대해 풀 메모리 덤프를 떴습니다.

그중에 문제의 원인인 듯한 패키지(IntelGfxDebug.IntelGfxDbgPackage)가 하나 눈에 띕니다. "Tools" / "Extensions and Updates..." 메뉴로 들어가면 Intel 관련해서 (제 경우에는) 다음의 패키지가 2개 있습니다.
 
이 중에서 "Intel adapted Microsoft MI-based Debugger"는 제작자가 "Microsoft"인 반면, "Intel Debugger for Heterogeneous Compute"는 "Intel"이 만든 것이었습니다. 대개 이런 경우 제 경험상 ^^ 마이크로소프트보다는 3rd-party 제작자의 확장이 문제를 일으켰습니다. 예상은 빗나가지 않아서, 실제로 "Intel Debugger for Heterogeneous Compute" 확장을 "Disable" 시킨 후부터는 오류 메시지가 더 이상 나타나지 않았습니다. (IntelGfxDebug.IntelGfxDbgPackage.Initialize 메서드가 호출되지 않을 테니 당연한 결과입니다.)
참고로, Visual Studio 2017로 오면서 Redgate의 확장이 기본적으로 몇 개 설치가 됩니다. "Tools" / "Extensions and Updates..." 메뉴로 들어가도 "Revert" 메뉴는 있어도 "삭제(Uninstall)" 메뉴는 없는데요. 이것을 삭제하려면 "Tools" / "Get Tools and Features..." 메뉴로 들어가서 "Individual components" 탭의 "Cloud, database, and server" 범주에 다음의 항목들이 있는데,
 
- SQL Prompt Core
- SQL Search
- Redgate SQL Change Automation Core
이들의 체크 박스를 해제하시면 됩니다.
