django 4 recent issue

Question

Django has recently released a new version and I'm trying to work with it. But the problem that I have is that one I say pip install Django no matter in the cmd or visual studio's cmd, it installs Django 4.0, but once I put the file in the code editor (it is vs code), it changes to Django 3.0 and I was shocked once I saw that even in pip freeze` it is changed! I would be so glad if you can help me with this problem
