Bug in async server?

[myclues]

Hello,
I recently added django-solo for an application settings singleton model, and I'm not sure if that's the root cause, but now I'm seeing an error with a stacktrace that references the solo model. I'm using Uvicorn/ASGI to take advantage of websockets fyi.

@myclues Would you be able to provide a minimal example app that demonstrates this?
