It appears that there's still something wrong in your environment, as I noted on the Ask question you linked where the OP had a similar issue for reasons that were never resolved as they failed to respond.
This is what I see when I start the Developer Command Prompt:
**********************************************************************
** Visual Studio 2019 Developer Command Prompt v16.3.9
** Copyright (c) 2019 Microsoft Corporation
**********************************************************************
C:\Users\Richard.Sharpe.A00187\source\repos>set PLATFORM
Environment variable PLATFORM not defined
The preliminary output in the prompt is missing the very important line:
[vcvarsall.bat] Environment initialized for: 'x64'
which shows that vcvarsall.bat was called and set the Platform env. var. This indicates something still isn't right about your environment. What do you have in "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\"?
