jinja2.exceptions.TemplateNotFound: index.html even though my index.html is in a "templates" folder

I’m learning how to code using python’s flask but I can’t seem to sucessfully run my server. For some reason, I keep getting Template not found but I do have my index.html in my templates folder just like flask wants me to. I’ve attached an image showing the folder. folders and error

I have tried using the "app = Flask("Web Translator", template_folder=’new folder name’)" and changing the folder name and replacing the template_folder="new folder name" but it does not work. When I try to run my server it shows this:enter image description here

    This is how you should create the Flask Object

    app = Flask(__name__, template_folder='new folder name')

    The __name__ variable is a special variable that represents the name of the current module. When you run a Python script directly, the __name__ variable is set to __main__.

    In the context of Flask, the __name__ variable is used to determine the root path of the application. It helps Flask locate the root directory of the project and find other files and folders relative to that path.

    Now after looking at your code, the page you want to render is in new folder nametemplateindex.html
    then your code shall work fine.

    return render_template('templates/index.html')

    In your code, you have return render_template('templates/index.html'). Flask will look for a folder called ‘templates’ within the default template folder.

    You should simply have it as return render_template('index.html')

    Also, conventionally, you do app = Flask(__name__). See this for an explanation on why
