Django // Daphne 500 error on all requests after version update "TypeError: object HttpResponse can't be used in 'await' expression"

I have a problem where I'm getting 500 responses after updating Django from version 3.1.13 to 3.2.8.

The issue wasn't occurring on the previous version of Django, and it only occurs if both the Django Channels app and OpenCensus middleware are enabled in settings.py.

I would really appreciate if someone can help verify that my asgi.py and settings.py are configured correctly, or identify the dependency causing the issue so that I can follow through and raise a bug.
