I suspect this is caused by the change to use ProactorEventLoop on Windows by default.

This'll need a fix in asgiref. Tracking at ​https://github.com/django/asgiref/issues/132

comment:5 by Carlton Gibson, 6 years ago

I created a ​PR on asgiref, that looks OK in testing. This may do until a fix lands in Python (???)

Tracking on CPython: ​https://bugs.python.org/issue38563
