Summary

After upgrading to 2.5.0, my program emits unexpected errors to log output.

Reproduction Steps

The code below works correctly with 2.4.1 and all previous versions:

class Client(discord.Client):
    async def on_ready(self):
        await self.wait_until_ready()
        logger.debug("Discord connection ready")
        
        # Do stuff here
        ...

        logger.debug("Closing Discord client")
        await self.close()

    async def on_error(self, event, *args, **kwargs):
        logger.debug("Got an error, raising")
        raise

client = Client(loop=asyncio.new_event_loop())

def exc_handler(loop, context):
    nonlocal exc
    exc = context.get("exception")
    logger.debug(f"Recording exception: {exc}")
    loop.default_exception_handler(context)
    logger.debug("Stopping async execution")
    loop.stop()

client.loop.set_exception_handler(exc_handler)
logger.debug("Starting")
client.run(DISCORD_API_KEY)

After upgrading to 2.5.0, it produces the following logging at the end of the output:

...
[custom_logger] DEBUG: Recording exception: None
[asyncio] ERROR: Unclosed client session
client_session: <aiohttp.client.ClientSession object at 0x10d2e83d0>
[custom_logger] DEBUG: Stopping async execution
[custom_logger] DEBUG: Recording exception: None
[asyncio] ERROR: Unclosed connector

[custom_logger] DEBUG: Stopping async execution

Minimal Reproducible Code

No response

Expected Results

The code I have is designed to spin up a Discord client, do something over the API, and then close the client and end the script. It catches any exceptions and lets them to bubble up to crash the script in case of errors. It's supposed to work as a one-time job, not as a long-running bot. This code has worked correctly for several years now. It still does, but with 2.5.0 it started to produce errors which indicate something suddenly ain't right.

Actual Results

Getting errors which indicate something suddenly ain't right.

Intents

not relevant, but it's Intents(guilds=True, members=True, message_content=True)

Checklist

• I have searched the open issues for duplicates.
• I have shown the entire traceback, if possible.
• I have removed my token from display, if visible.

Additional Context

I wanted to figure out what commits in pycord caused the errors, but there's 262 new commits in the new version and that's just too many for me to go through 🤯 So just hoping here you might have a hunch what could be the issue.
