Hi 🙂 Downloaded Processing 4 beta 4, tried running it from the terminal and I’m greeted with this window, then it closes. Ubuntu 21.04. Any ideas? Not urgent, just wondering if an issue should be created on GitHub.

Renaming the sketch folder didn’t help. Processing 3.5.4 works fine. Processing 4 beta 2 did launch, but showed errors in valid code.
