I am reinstalling psychopy on Ubuntu 20.04. It was previously working, but I had to reinstall after changing python versions. I believe I followed the installation directions
pip install psychopy pip install psychopy/wxPython-4.1.1-cp38-cp38-linux_x86_64.whl sudo apt-get install libusb-1.0-0-dev portaudio19-dev libasound2-dev
Everything seemed to install correctly. However, I get the following error when I try to run psychopy. Any ideas for a solution would be greatly appreciated.

Its timing is vastly superior. Your prefs are currently set to use ['sounddevice', 'PTB', 'pyo', 'pygame'] (in that order).
