Interpreter Python 3.8 not there to select from PyCharm

[Maxime Albi]

I'm very new to Python and wanting to learn the basics.
I downloaded and installed Python 3.8 and PyCharm for my Windows 10 machine.  All good.

Launched PyCharm and I started a new Project and tried to select an 'interpreter' such as Python 3.8 but no interpreter was available for me to select from the down arrow menu ..!?!?

Any settings I need to do ??

Thanks,
Maxime
