Download Psychopy 3.2.3

I’m trying to run an experiment using pavlovia and it doesn’t initialize when I use the 2020 version of Psychopy, but it works when my friend uses the 3.2.3 version. I want to download this version so that I can continue working on the experiment, but I don’t know how. I tried to get files from GitHub but it didn’t work. Does anyone have advice for how to do this for someone who is new to GitHub?
