Python 3.9 run Windows Server 2008 problem

According to https://www.python.org/downloads/windows/:
Python 3.9 cannot be used on Windows 7 or earlier.
But we had a server with Windows Server 2008 R2 installed 🤷 and while running a project with Python 3.9 on Windows Server 2008 R2, we encountered the following issue: 
python.exe run.py exited with -1073740777. It is Unknown Software Exception: 0xc0000417.
Failed process printed the next output:

D:\Jenkins\workspace\TEST>"D:\Jenkins\workspace\TEST\project\python.exe" run.py
Python path configuration:
  PYTHONHOME = (not set)
  PYTHONPATH = (not set)
  program name = 'D:\Jenkins\workspace\TEST\project\python.exe'
  isolated = 0
  environment = 1
  user site = 1
  import site = 1
  sys._base_executable = '\xc5V\u3241Z'
  sys.base_prefix = '.'
  sys.base_exec_prefix = '.'
  sys.platlibdir = 'lib'
  sys.executable = '\xc5V\u3241Z'
  sys.prefix = '.'
  sys.exec_prefix = '.'
  sys.path = [
    'D:\\Jenkins\\workspace\\TEST\\project\\python39.zip',
    '.\\DLLs',
    '.\\lib',
    '',
  ]

The variables sys._base_executable and sys.executable are corrupted and filled with arbitrary data.

We had sitecustomize.py file, with sys.executable variable update to required python.exe, but the problems still reproduced.

The only solution helped:

It is required to set the next environment variables (in our case we set them in Jenkins):

set PYTHONPATH=%PYTHONPATH%;%WORKSPACE%\project

set PYTHONHOME=%PYTHONHOME%;%WORKSPACE%\project

set __PYVENV_LAUNCHER__=%WORKSPACE%\project\python.exe
