Checklist

• [ x] The error is in the library's code, and not in my own.
• [ x] I have searched for this issue before posting it and there isn't a duplicate.
• [ x] I ran pip install -U https://github.com/LonamiWebs/Telethon/archive/v1.zip and triggered the bug in the latest version.

I ran this code a week ago and everything worked perfectly, but now that I’m running it, I keep getting this bug and the same current telegram session on all my devices goes missing and leaves my account

Code that causes the issue

from telethon.sync import TelegramClient
import config

client = TelegramClient('anon', api_id, api_hash)
client.start()
chat_id = config.chat_id
chat_id2 = config.chat_id2

@client.on(events.NewMessage(chat_id))
async def main(event):
    await client.forward_messages(chat_id2 , event.message)

client.run_until_disconnected()

Traceback

telethon.errors.rpcerrorlist.SessionRevokedError: The authorization has been invalidated, because of the user terminating all sessions (caused by GetDifferenceRequest)

This error comes from Telegram. It's not something Telethon can fix. See #4051.
