I get error This site can't be reached - Django?

Question

Django

I get an error

This site can't be reached

and pop up window

python quit unexpectedly

when starting a project on Django

All other projects work without problems except for this particular project.

Tried all possible solutions like starting the server as 127.0.0.1:8000 , 0.0.0.0:8000 , or localhost:8000 , changed ALLOWED_HOST = ['*'] and ['127.0.0.1'] but none of them work.

here is my settings.py

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

Answer 1

"python quit unexpectedly" for some reason, python itself crashes, it's hard to say what the reason is. If you create a new project, does it start? If so, then start disabling one app at a time for this project and try to start it, maybe there are problems in them.
