Telegram bot continues to process the request instead of restarting

Question

There is a working Telegram bot that sends a greeting and offers to submit a request. It sends the result to a specific user in a Telegram chat.

However, if during the request submission process, the user stops 'halfway', clears the history, and restarts the bot with the /start command, the bot does not start from the beginning but continues to process the request.

Also, if the user has submitted a request, there is no possibility to submit a new one.

Please help adjust the code so that if /start is pressed while the bot is performing a task, it starts from the beginning.

And so that when a request is created and sent, there is the possibility to immediately create a new request.

bot.polling(none_stop=True)

If /start is pressed while the bot is performing a task, it starts from the beginning.
