_winapi.CreateProcess PermissionErro

Hello ，
I try to use a bat file to run pyFluent code, but have a problem:

1、bat:
pushd %~dp0

set PYTHON_EXEC="C:\Anaconda311\python.exe"
set EMCCFD_PACKAGE_DIR="\file-sh04\hpc\UAES\00.SPDM\122.ModuleCFD"

%PYTHON_EXEC% -c "import sys;sys.path.append(r'%EMCCFD_PACKAGE_DIR%');from modulecfd.pyFluent_macro import post_processing,create_report;post_processing(r'%cd%');create_report(r'%cd%')"
set RETURN_CODE=%errorlevel%

popd
pause
exit /b %RETURN_CODE%

2、pyFluent code:
def post_processing(working_dir):
solver = pyfluent.launch_fluent(
product_version="23.2.0",
precision="double",
processor_count=1,
mode="solver",
cleanup_on_exit=True,
show_gui=False,
additional_arguments='-post'
)

3、Error message:
C:\Anaconda311\Lib\site-packages\paramiko\transport.py:219: CryptographyDeprecationWarning: Blowfish has been deprecated and will be removed in a future release
"class": algorithms.Blowfish,

The above exception was the direct cause of the following exception:

Can you give me some information that may cause this problem？ Thanks in advance

Can you please try with:

solver = pyfluent.launch_fluent(
product_version="23.2.0",
precision="double",
processor_count=1,
mode="solver",
cleanup_on_exit=True,
show_gui=False,
additional_arguments='-post',
start_watchdog=False
)
