Here a few tips that can help you to fix your problem:

1. You need to make sure that the OS is compatible with the Python version. For example, if you're using Windows 7, then Python 3.12 is not compatible with the OS version.
2. Second, check for errors that VSCode is giving you.
3. Make sure you installed the Python Extension, as told in the Quick Start Guide for Python in VS Code.
4. Make sure you inserted a Python Interpeter in the IDE.
