Option 1:
delete and reinstall again. and then when creating a project it should prompt you to pick a basic interpreter, choose python310 or whatever version you're using.
Option 2:
use a different IDE.
My issue requires some backstory.
I was having some troubles with pip, so I reinstalled Python.  After the reinstall pip began to work, but Pycharm, my IDE, could no longer find Python.  When I reinstalled Python it created a new folder for itself (Python310), but Pycharm kept looking in the old folder (Python39).  I couldn't figure out how to get Pycharm to look in the new folder.  Even deleting and reinstalling it did nothing.
So, I renamed Python310 to Python39 and changed the PATH.  Now Pycharm can find Python.  But pip has developed a new and exciting error.  When I try to use it I get the following message:
Fatal error in launcher: Unable to create process using '"C:\Users\user\AppData\Local\Programs\Python\Python310\python.exe"  "C:\Users\user\AppData\Local\Programs\Python\Python39\Scripts\pip.exe" install numpy': The system cannot find the file specified.
If I read this correctly pip is still trying to look in Python310.  Would you please tell me what I need to do to get pip to looking in the right place?
pip looking in wrong folder
