New version of Visual Studio 2026 gives internal compiler error when compiling reflect.h

I installed the new Visual Studio 2026, and last I checked reflect.h from reflect-cpp was compiling, but no longer. It gives a internal compiler error C1001.

The version I'm using is 18.0.2 (from the about Help->About page).

Here is a link to a Godbolt setup that includes the reflect.h file, and compiles on the latest one there, which is not as new as the one I downloaded.
