Fix Frequent Crashes of Telegram Checker

My Telegram checker, built with Python, is experiencing frequent crashes during startup. It's crucial for this software to be stable and reliable for my needs. I haven't made any recent changes or updates to the code or the libraries, so the issue is likely embedded in the software itself.

Ideal Skills:
- Proficiency in Python programming
- Experience with Telegram bots or checkers
- Debugging skills
- Knowledge of software stability improvements

I am looking for a freelancer who can identify the cause of the crashes and implement a fix. Please provide examples of similar projects you've worked on.
