[Python] Error messages clogging Telethon resulting in security error: Server sent a very new...

I am really at a loss here, recently migrated to new machine and telethon has just broken down it seems. I've checked with others, so its probably just me, but I can't figure out how to solve this problem as it appears to be server side/telethon, but as it seems to be on my end it doesn't seem so obvious.

Whenever launching telethon from an existing session I receive two error messages:

Server sent a very new message with ID xxxxxxxxxxxxxxxxxxx, ignoring
Server sent a very new message with ID xxxxxxxxxxxxxxxxxxx, ignoring
​

And thereafter it gets clogged with the follow error messages, preventing any execution:

[WARNING/2022-09-07] telethon.network.mtprotosender: Security error while unpacking a received message: Too many messages had to be ignored consecutively
​

I've attached some standard code which reproduce this error for me. Could someone please give me a heads-up on whats causing this? And what to do about it? Running 3.10 Python and latest Telethon from pip.

from telethon import TelegramClient, events
from telethon.sessions import StringSession

api_id = 1xxxxxxxxxx
api_hash = '2xxxxxxxxxxxxx'
ph = '+1xxxxxxxxxxxxxxxx'
key = 'xxxxxx...'

#client = TelegramClient('session', api_id, api_hash).start(phone = ph)
client = TelegramClient(StringSession(key), api_id, api_hash).start(phone = ph)

channelId = 'xxxxxxx'

@client.on(events.NewMessage(chats = [channelId]))
async def main(event):
try:
me = client.get_me()
print(me.stringify())
print(event.stringify())
except Exception as e:
print(e)


client.run_until_disconnected()
