RuntimeError: Event loop is closed

The code :

    import discord
    client = discord.Client()
    @client.event
    async def on_ready():
        try :await client.close()
        except : None


    client.run("token here" , bot=False) #Using None-Bot account

I tried :

• handling on client.close() .
• stopping the event loop before quit but i failed .

Note : The token is correct and the bot runs correctly and raises the exception after the await bot.close() directly .

It seems to be the Windows EventLoopPolicy that raise this error.

You can do the following:

import asyncio
import discord
import platform

client = discord.Client()

@client.event
async def on_ready():
    # Set the current process-wide policy
    if platform.system().lower() == 'windows':
        asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())
    
    try: await client.close()
    except: None


client.run("token here")

For more information you should have a look about policies on the asyncio/Policies documentation.
