Additional Information

I also tried this solution but got the following error

Traceback (most recent call last):

UPDATE:

self.loop = asyncio.WindowsSelectorEventLoopPolicy().get_event_loop()
super().__init__(command_prefix=self.PREFIX, strip_after_prefix=True, case_insensitive=True, loop=self.loop)

This worked for me but now, When trying to await self.wait_until_ready() I get the following error

Traceback (most recent call last):

Try updating to python 3.9.

This has gone stale and isn't something I can resolve in the library. Closing.
