attribute error in Flask when I run (AttributeError: 'NoneType' object has no attribute 'run' )

I'm Doing the tutorial (https://www.youtube.com/watch?v=dam0GPOAvVI&t=2412s) it was working nicely since there was a problem I don't what.When I run the main.py

Traceback (most recent call last):
  File "c:\Users\admin\Documents\Flask\main.py", line 6, in <module>
    app.run(debug=True)
AttributeError: 'NoneType' object has no attribute 'run'
PS C:\Users\admin\Documents\Flask>

And the website isn't comming

This site can’t be reached
127.0.0.1 refused to connect.

It will really helpful if u find out why I'm struglling with it Flask/main.py

from website import create_app

app = create_app()

if __name__ == '__main__':
    app.run(debug=True)

website/init.py

from flask import Flask

def create_app():
    app = Flask(__name__)
    app.config['SECRET_KEY'] = 'hello'

    from website.views import views
    from website.auth import auth

    app.register_blueprint(views, url_prefix='/')
    app.register_blueprint(auth, url_prefix='/')

website/views.py

from flask import Blueprint, render_template  

views = Blueprint('views', __name__)

@views.route('/')
def home():
    return render_template("home.html")

website/auth.py

from flask import Blueprint, render_template  

auth = Blueprint('auth', __name__)

@auth.route('/login')
def login():
    return render_template('login.html')

@auth.route('/logout')
def logout():
    return "<p>Logout</p>"

@auth.route('/sign-up')
def sign_up():
    return render_template('sign_up.html')

At the end of website/init.py, you need to include

def create_app():
    # your other code

    return app # add this

create_app() in Flask/main.py currently returns nothing (None).
