How to fix "sys.stderr is None" after compiled a script with Pyinstaller --noconsole?

ENVIRONMENT

Windows 10

Python 3.10

Pyinstaller 5.9

PROBLEM:

I am trying to compile a script that needs to run some command lines in the console in order to get some values from the system.

if __name__ == '__main__':
    faulthandler.enable()
    try:
        proc = subprocess.Popen(p_command, shell=True, stdout=subprocess.PIPE, stdin=subprocess.PIPE,
                                stderr=subprocess.STDOUT, close_fds=True)
        output, errors = proc.communicate()
    except:
        pass

You can use this code above to reproduce the error.

When I compile with the console, the "exe" works fine.
When I compile with "--noconsole", the "exe" failed with this error message :

Traceback (most recent call last):
  File "script.py", line 5432, in <module>
    faulthandler.enable()
RuntimeError: sys.stderr is None

After a few hours of investigation, I've understood the stdin and stdout arguments from the code "subprocess.Popen) can't be used with "--noconsole" compilation mode.
I tried this solution :

stream = io.StringIO()
sys.stdout = stream
sys.stderr = stream

But it still doesn't work.
I verified the doc:
https://readthedocs.org/projects/pyinstaller/downloads/pdf/stable/
It clearly said :

> (Windows) In windowed/noconsole mode, stop setting sys.stdout and
> sys.stderr to custom NullWriter object, and instead leave them at
> None. This matches the behavior of windowed python interpreter
> (pythonw. exe) and prevents interoperability issues with code that
> (rightfully) expects the streams to be either None or objects that are
> fully compatible with io.IOBase. (#3503)

So the solution N°1 seems correct, doesn't it?

I didn't have this issue last year when I compiled the previous version. I don't understand why now there is this issue.

Does anyone have any solution to this issue PLEASE?

It seems you are running into a RuntimeError because sys.stderr is None. The faulthandler module needs a valid stderr stream to report errors. This can occur when your Python script is executed in an environment where the standard error stream (sys.stderr) is not properly set up or is missing.

To fix this issue, you can try one of the following:

Set up a valid stderr stream before enabling the faulthandler:

import sys
import os
import faulthandler
import subprocess

if sys.stderr is None:
    sys.stderr = open(os.devnull, 'w')

if __name__ == '__main__':
    faulthandler.enable()
    try:
        proc = subprocess.Popen(p_command, shell=True, stdout=subprocess.PIPE, stdin=subprocess.PIPE, stderr=subprocess.STDOUT, close_fds=True)
        output, errors = proc.communicate()
    except:
        pass

Alternatively, if you want to see the error output, you can set sys.stderr to sys.stdout:

if sys.stderr is None:
    sys.stderr = sys.stdout
    ....
