Python Discord: RuntimeError: Event loop is closed when launched from a specific network

Question

RuntimeError: Event loop is closed error when trying to run any bot in discord when connected to my wifi network. When connected to another network, everything works as it should.

Code example:

import discord
from discord.ext import commands

bot = commands.Bot(command_prefix='!', intents=discord.Intents.all())

bot.run(TOKEN)

I am getting the above error when trying to run this code. I am accurately passing the correct access token and have all intents enabled:

I'm using py-cord, but the problem also occurred when using the discord-py library.

I have the latest version of py-cord==2.0.0b7 installed using the command

pip install git+https://github.com/Pycord-Development/pycord

If the problem occurs only in a specific Wi-Fi network, it is probably worth trying to restart the router - this was the solution to the problem
