Error generating header file. Make sure project builds

[zrajnai-shapr3d]

Describe the bug
Right clicking on an idl file in solution explorer and clicking on "Update Header File..." produces the error "Error generating header file. Make sure project builds"
My project builds fine.

Opening the developer command prompt, I can execute cppwinrt. Version displayed in the cmd prompt is : C++/WinRT v2.0.201201.7

Are there any logs perhaps that could help with debugging this issue?

I see this as well, it does have a log file off of AppData but the information it is providing doesn't really help. My best guess is it is making a LOT of assumptions about output locations without using the proper MSBuild macros to locate/find things. In my case I have a Directory.Build.[Props|targets] to customize the entire repository build. That includes re-dierection of ALL build output to a specific location distinct from the rest of the source tree. This keeps the source tree isolated from the build output and it is trivially easy to "clean" the whole repo.
