Qt cannot get MSVC environment. What's wrong?

Question

Qt

For some reason Qt can't get the MSVC environment.
When QtCreator is launched, errors are immediately displayed in the console:


The second line in the error message is very similar to PATH. I searched for information, looked at PATH - not that, it's ComSpec.
There seems to be something wrong with the ComSpec. Perhaps I accidentally mixed up with PATH and wrote the wrong values ​​there ...
Can someone please throw off the contents of this variable?

My PATH:
C:\Program Files\Python38\Scripts\;
C:\Program Files\Python38\;
C:\Program Files (x86)\Common Files\Oracle\Java\javapath;
C:\Windows\system32;
C:\windows;
C:\Windows\System32\Wbem;
C:\Windows\System32\WindowsPowerShell\v1.0\;
C:\Program Files\Git\cmd;
C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;
C:\Qt\5.14.1\mingw73_64\bin;
C:\Qt\5.14.1\mingw73_32\bin;
C:\Program Files\CMake\bin

ComSpec:
C:\Windows;
C:\Windows\System32;
C:\Windows\System32\Wbem;

Or is there another solution?
