sqlite3.OperationalError: database is locked

[ForelliCH]

Code that causes the issue

`from telethon import TelegramClient
import json
import os
from tw_func import *

tw_filename = "tw_crwlr_prd.py"

tw_filename = os.path.basename(file)[:-3]
tw_function_crwlr_workdir(tw_filename)

with open("tw_conf.json", 'r') as f:
tw_conf = json.load(f)

api_id = "xxxxxxx"
api_hash = "xxxxxxxxxxx"

tw_telclient = TelegramClient("tw_crwlr_telegram", api_id, api_hash)

group_name = "gemcomm"

async def save_messages():
await tw_telclient.start()
messages = await tw_telclient.get_messages(group_name, limit=10)
tw_data = ""
for message in messages:
tw_data += f"{message.sender_id}: {message.text}\n\n"
await tw_telclient.disconnect()
return tw_data

with tw_telclient:
tw_data = tw_telclient.loop.run_until_complete(save_messages())

print(tw_data)`

Expected behavior

I have a development environment with Windows 10 and Python 3.8 where I tested the code. It works without any issues. Then, I exported the script to a Linux (Ubuntu 20.04.6 LTS) environment with Python 3.8. There, the aforementioned error occurred immediately. In the new environment, there was no session file present; it was completely new. I then tested with Linux (Ubuntu 23.10) and Python 3.11 as well. Same problem.

Actual behavior

The error message appears. By the way, the session file remains 0KB in size. It doesn't seem like anything is being written to it. I then gave one of these 0KB files full permissions (777), but that didn't help either. The existing entries are unfortunately not helpful. It is indeed a new system, with no open processes.
