How did you install Python? (What instructions or tutorial did you follow? Does python itself work?)

From the screenshot you have given I can see that you have installed Django globally and then create venv, activated it, then in python’s virtual environment you are trying to start the Django project.
Do one thing pip install django again in the activated python’s virtual environment i.e in your case is django.
