mod_wsgi django not working with Apache24

Question

I am using a MS Windows 11 Machine running Python 3.11 with virtualenv package installed.

I am using Apache24 httpd.exe web server for my django app production server.

My app is called mysite and it is fully functional inside a virtual environment (called venv) with the folowing packages (requirements.txt):

django
django-extensions
django-iprestrict
mod-wsgi
Pillow
pyOpenSSL
odfpy
werkzeug
whitenoise
pandas
plotly
matplotlib

I can fully run the server in DEBUG mode with the virtual environment activated:

(venv) python.exe manage.py runserver

And, on the other hand, I was able to make the Apache web server to run a test website without problems.

The issue is when I edit httpd.conf files to integrate with my django app thorugh mod_wsgi:

# httpd.conf

(...)

LoadFile "C:/Users/myuser/AppData/Local/Programs/Python/Python311/python311.dll"
LoadModule "C:/Users/myuser/mysite/mysite_venv/venv/Lib/site-packages/mod_wsgi.cp311-win_amd64.pyd"

WSGIScriptAlias / C:\Users\myuser\mysite\mysite\wsgi.py
WSGIPythonHome C:\Users\myuser\mysite\mysite_venv\venv
WSGIPythonPath C:\Users\myuser\mysite

<Directory />
<Files wsgi.py>
Require all granted
</Files>
</Directory>

# media files hosting

Alias /media "C:/Users/myuser/mysite/media/"

<Directory "C:/Users/myuser/mysite/media/">
Require all granted
</Directory>

(...)

My directory tree is:

│   ├── apps.py

│   ├── __init__.py

    ├── css
    ├── django_extensions
    ├── font
    ├── icon
    ├── javascript
    ├── js
    └── uploads

The issue is when I run httpd.exe the web page loads forever because the server does not respond the client.

I have opened the error.txt log file from Apache to find out what is going on, but there was any error message about anything.

I took care about:

setting PYTHONPATH environment variable to the DLLs as described here
natively compile and place the mod_wsgi .pyd in the correct path.

Can someone help me what is going on? Thanks in advance!

There is some issue/conflict between modules plotly and mod_wsgi that stucks the HTTP/S requests when Apache24 loads the plotly module through WSGI.

The same thing happens with pandas module, too.

I could fix this problem by commenting all views and urls that loads these modules.

There is no problem about virtualenv having these modules installed, the issue is that they cannot be loaded by mod_wsgi.

The big question is that the development server works with them through python manage.py runserver, the issue is exactly when you put the server in production mode.
