[Python] Error occurred while reading WSGI handler: Error

when I want to open the django project, I encounter such an error. My django projects are live on the same server, but I encountered such an error on the last site I opened.

web.config:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<handlers>
<add name="Python FastCGI" path="*" verb="*" modules="FastCgiModule" scriptProcessor="c:\python39\python.exe|c:\python39\lib\site-packages\wfastcgi.py" resourceType="Unspecified" requireAccess="Script" />
</handlers>
<tracing>

<appSettings>

</appSettings>
<system.web>
<compilation tempDirectory="C:\Inetpub\vhosts\domain.com\tmp" />
</system.web>
</configuration>


The error I get is about;
