VSCode + MSVC: Unable to open 'throw.cpp' (or exe_common.inl): File not found

Question

I am using MSVC+VSCode to compile C++ Program with cl+nmake for comparable operations on gcc+make. The build with nmake seems okay after some trouble with tasks.json, c_cpp_properties.json, etc. But I encountered problems during debugging, which may involves setup of launch.json around "sourceFileMap", but I'm not sure what to do with it properly. If the program is bug-free, upon exiting it pops Unable to open 'exe_common.inl': File not found and if clicking Create File it creates an empty file at {Disk}/a01/..., a strange directory. If encounters a bug and throw an exception, it pops Unable to open 'throw.cpp': File not found and does the same. I suppose it wants to locate the files under ...\VC\Tools\MSVC\14.29.30133\crt\src\vcruntime since I could find the files VSCode mentions, but don't know how to address it. I haven't found the very similar posts addressing the solution. How could I get it resolved?
