Why can there be 500 internal server error after installing django-cors-headers?

Question

Django

Hello!
I uploaded it to the combat server via pip dajngo-corsheaders.
Added to settings.py in INSTALLED_APPS and in MIDDLEWARE_CLASSES the corresponding entries.
I restarted uwsgi (at that moment the virtual environment was active)
Now when I access the site I get 500 internal server erorr I
don’t see anything in the nginx logs ((
Removed cors-headers via pip and returned settings.py to the current state. Restarted uwsgi, server, by still getting 500
