Hi there,

The issue here is that the version of Sonic Pi (v3.1) that is bundled with the Raspberry Pi (and provided in the Raspberry Pi software repository) is a version that was built outside of our control, and is partially broken.
You can get a working version of Sonic Pi running on your Raspberry Pi, but in order to do so, here's what you need to do:

• Uninstall the built-in Sonic Pi v3.1
• Download the latest version from our own website: https://sonic-pi.net
• Double click on the downloaded file to install it (and enter the Pi user's account password when prompted)
• Reboot your Raspberry Pi

This should then mean you have a fully up-to-date and working Sonic Pi 👍
