Why is my asynchronous python script stopping executiuon

So, I am wanting to make all the lines in a text file send a request to the twitch login api to get their IDS, now there is about 10k lines in this text file and I want to send them in parallel but my current code stops the code execution at print(“Sending Request”) and then it moves onto the next line in the text file.

If I run the code one at a time like asyncio.run() it works just fine but this is really slow. Anyone I can make these requests run parallel?

async def get_id(sem, username, oauth):
    """
    Hit the login endpoint so we can get the ID of each account we have. This will allow us to use the new twitch api.
    """
    async with sem:
        Oauth = oauth
        oauth = f"Bearer {oauth}"
        async with aiohttp.ClientSession() as session:
            try:
                print("Sending Request")
                get_userID = await session.get('https://api.twitch.tv/helix/users?login=' + username, headers={'Client-Id':'kimne78kx3ncx6brgo4mv6wki5h1ko', "Authorization": oauth})
                parse_response = await get_userID.json()
                print("Got Response")
                USERID = parse_response["data"][0]["id"]
                print("Got USERID")
                print(f"Username: {username} | ID: {USERID} | Oauth: {Oauth}")
                """
                This function writes our ID and some other useful info from the twitch api to the file.
                """
                cwd = os.getcwd()
                async with aiofiles.open(f"{cwd}/accounts/working_accounts.txt", mode="a") as accountFile:
                    await accountFile.write(f"{username}:{USERID}:{Oauth}\n")
            except:
                pass

async def run():
    sem = asyncio.Semaphore(limit)
    cwd = os.getcwd()
    ACCOUNTS = await read_file(f"{cwd}/accounts/accounts.txt")
    """
    Our for loop to make a new coroutine for each line in our text file. (approx 10k)
    """
    tasks = []
    for account in ACCOUNTS:
        formatAccount = account.split(":")
        username = formatAccount[0].replace("\n", "")
        oauth = formatAccount[1].replace("\n", "")
        task = asyncio.ensure_future(get_id(sem, username, oauth))
        tasks.append(task)
    response = await asyncio.gather(*tasks)

if __name__ == "__main__":
    loop = asyncio.get_event_loop()
    loop.run_until_complete(asyncio.ensure_future(run()))
