Enabling channels leads to SuspiciousFileOperation at /

Question

I noticed that whenever I enable django channels in my code, I get the following error, when I run the server:

SuspiciousFileOperation at /

The joined path (C:\favicon.ico) is located outside of the base path component.

Error during template rendering

Following changes in settings.py produce the error:

INSTALLED_APPS = [
    "channels",
    "django.contrib.admin",
    "django.contrib.auth",
    "django.contrib.contenttypes",
    "django.contrib.sessions",
    "django.contrib.messages",
    "django.contrib.staticfiles",
    "debug_toolbar",
    "corsheaders",
    "rest_framework",
    "rest_framework.authtoken",
    "core",
    "drf_yasg2",
]

WSGI_APPLICATION = "app.wsgi.application"
ASGI_APPLICATION = "app.asgi.application"

Following changes in asgi.py produce the error:

import os

from channels.routing import ProtocolTypeRouter
from django.core.asgi import get_asgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "app.settings")

application = ProtocolTypeRouter({
    "http": get_asgi_application(),
    # Just HTTP for now. (We can add other protocols later.)
})

In my case, the issue was caused by browser cookies, clearing the cookies makes my code work again!
