Just uninstall all stuff of python 1st. Then delete that file from pc. Then uninstall python interpreter and download python form its official page again and install it and also install python interpreter again then
Check it in your cmd or powershell is it running perfectly or not.
It will definitely run.
I am getting the same problem but it was resolved now.
python 3.8 and pip gives this error[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate is not yet valid (_ssl.c:1123)')))
