init_fs_encoding: failed to get the Python codec of the filesystem encoding

Question

I'm running Django website on apache.

Here is the tail of my httpd.conf file.

ServerName 127.0.0.1:8080


# Django Project
LoadFile "c:/python39/python39.dll"
LoadModule wsgi_module "c:/python39/lib/site-packages/mod_wsgi/server/mod_wsgi.cp39-win_amd64.pyd"
WSGIPythonHome "c:/python39/"
WSGIScriptAlias / "C:/pd_videowebapp/mysite/wsgi.py"
WSGIPythonPath "C:/pd_videowebapp/"

<Directory "C:/pd_videowebapp/mysite/">
    <Files wsgi.py>
        Require all granted
    </Files>
</Directory>

Alias /static "C:/pd_videowebapp/static/"
<Directory "C:/pd_videowebapp/static/">
    Require all granted
</Directory>

And here is the tail of the error.log file:
