Use a stable version

PsychoPy is under constant development, with two new major releases every year. Inevitably some of the new features can introduce bugs elsewhere so you should treat the 20xx.x.0 release as a beta test version and, the final release of each year as the most stable.

Some of my favourite versions are 1.90.3, 2020.2.10, 2021.1.4, 2021.2.3, 2022.2.5 (recommended for eye tracking if you are having issues with the plugins introduced in 2023), 2023.2.3 (recommended for Windows 7), 2024.1.4 (may avoid recent Mac installation issues) and 2024.2.4. If you are using any of them you should be fine, so long as you don’t need later features.
