[Python] Pycord cog loading gives TypeError: object NoneType can't be used in 'await'...

I'm writing a Discord bot using Pycord, and I'm trying to dynamically load cogs with an async def setup(bot) method.

Here's the relevant part of my main.py:

async def main():
for filename in os.listdir("cogs"):
if filename.endswith(".py"):
cog_path = f"cogs.{filename[:-3]}"
print(f" Importing {cog_path}")
try:
module = importlib.import_module(cog_path)
setup = getattr(module, "setup", None)
print(f" Checking setup in {cog_path}: {setup}")
print(f" Type of setup: {type(setup)}")

if setup:
if inspect.iscoroutinefunction(setup):
await setup(bot)
else:
print(f"⚠️ Skipped setup for {cog_path} because it's not async.")
except Exception as e:
print(f"❌ Failed to load {cog_path}: {e.__class__.__name__} - {e}")

await bot.start(TOKEN)


And here’s the trivia.py cog:

async def setup(bot):
await bot.add_cog(Trivia(bot))


I get the following error at runtime:

TypeError: object NoneType can't be used in 'await' expression


Even though the setup function is async and the cog is implemented correctly.

I'm using Pycord Version: 2.6.1 in a WSL environment, not discord.py, and I confirmed that setup is a coroutine function via inspect.iscoroutinefunction(setup).

Questions

1. 
   Why would I be getting NoneType in await setup(bot) even when it's async?
   
   
2. 
   Is there something different about Pycord's cog loading I should be aware of?
