Unable to exit normally when fast is set to True and use nextcord(discord.py).

See original GitHub issue

Describe the problem When I use fast=True on sanic.Sanic and use nextcord that forked discord.py and I stop program by Ctrl + C, I keep getting this error and can’t quit.
What could be the cause of this?

Code snippet I’m not sure where to point you, so I’ve included the URL of the repository where all the code is located.

Expected behavior I want to make sure that it exits normally.
