I think that the problem is that you're trying to build from a regular cmd.exe? The code here: https://github.com/llvm/llvm-project/blob/d480f968ad8b56d3ee4a6b6df5532d485b0ad01e/clang/lib/Driver/ToolChains/MSVC.cpp#L1341 is unable to detect your version of MSVC in the PATH, so it just puts version 19.11 arbitrarily.

What value is your `%VCToolsVersion%` or `%VSCMD_VER%` ?

Can you try running from a "x64 Native Tools Command Prompt for VS 2019" shell?
