The error indicates that you need to create the database instances before running the app.

I am able to fix that and create new user and login the user by creating the tables before running the app in the run.py file:

from Main import app, db

if __name__ == '__main__':
    with app.app_context():
        db.create_all()   
    app.run(debug=True)

Demo:

Disclaimer: The project seems like a toy project and has a lot of bugs here and there (e.g. fixed dataset path).
