AttributeError: 'SSLProtocol' object has no attribute 'data_received' inside Toga.App, but in vanilla not

Describe the bug

When I tried to open a ws throw briefcase it breaks, but the same code works perfectly.
It happens:

Exception in callback ReadTransport._loop_reading(<Future finis...\x00\x00\x00'>)
handle: <GLibHandle ReadTransport._loop_reading(<Future finis...\x00\x00\x00'>)>
Traceback (most recent call last):

    self._context.run(self._callback, *self._args)

    self._protocol.data_received(data)
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'SSLProtocol' object has no attribute 'data_received'

I have prepared a dummy demostration script for that reason:

import aiohttp
from aiohttp import ClientSession

import asyncio

url = "wss://demo.piesocket.com/v3/channel_123"

ws_headers = {
    'Origin': 'https://www.piesocket.com',
    'Sec-WebSocket-Extensions': 'permessage-deflate; client_max_window_bits',
    'Sec-WebSocket-Version': '13',
    'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) '
                  'AppleWebKit/537.36 (KHTML, like Gecko) '
                  'Chrome/90.0.4430.212 Safari/537.36',
}

async def run_init_conversation(prompt="hello world!", cookies = ''):
    async with ClientSession(headers=ws_headers, cookies=cookies, timeout=aiohttp.ClientTimeout(total=60)) as session:
        async with session.ws_connect(url, autoping=False, params={'api_key': "VCXCEuvhGcBDP7XhiJJUDvR1e1D3eiVjgZ9VRiaV"}) as wss:
            print("Connected to test")


if __name__ == '__main__':
    asyncio.run(run_init_conversation())

or simply add this code to a dummy Toga App:

self.add_background_task(self.background)

and the definitions:

    def background(self, widget, **kwargs):
        task = self.run_init_conversation()
        asyncio.run_coroutine_threadsafe(task, self.loop)

    async def run_init_conversation(self, prompt="hello world!", cookies = ''):
        async with ClientSession(headers=ws_headers, cookies=cookies, timeout=aiohttp.ClientTimeout(total=60)) as session:
            async with session.ws_connect(url, autoping=False, params={'api_key': "VCXCEuvhGcBDP7XhiJJUDvR1e1D3eiVjgZ9VRiaV"}) as wss:
                print("Connected to test")

Steps to reproduce

briefcase build linux
briefcase run linux
Execute the code attached

Expected behavior

in screen it should print Connected to test but weird exception appears

Duplicate of beeware/gbulb#116.

The immediate workaround is to downgrade to Python 3.10 or earlier.
