Research direction
Reproduce the failure with the C++ example at https://godbolt.org/z/jdbGr7TTo and inspect the logged Natvis typename parsing error for nlohmann::basic_json. Trace the Natvis parsing entry point from that failure; done means this typename is parsed without the reported error and the debugger can display the value.
