Error after running my summarizer app

I recently made an article summarizer app on Streamlit. When I deploy it and test it for the first time, it works. But as soon as I exit the app, it stops working. I’ve tried twice to reboot it, but the same thing still happens. Can anyone help?

Here’s the GitHub repository for the app: GitHub - Dawudis/Streamlit-Article-Summarizer-App: My first Streamlit app..
