Solution.
1, ensure that when installing VS, the compiler for C++ is installed (you can test it by directly creating a new project with VS and checking whether the compilation passes).
2. Check the installation options for Windows 8.1 SDK and UCRT SDK (the default is unchecked)
3. Make sure that the correct compilation version is selected when coexisting with multiple versions of VS.
