NullPointerException when selecting port after running PDE in Linux #124

Open kierannolan opened 1 year ago

kierannolan commented 1 year ago

Hello,

When I run the p5.serialserver PDE and select the Arduino port from the drop down menu the app crashes. Please see the screenshot and error log below.

I'm running Processing 4 on Manjaro

Any suggestions on a bug fix would be greatly appreciated, thank you
