Anything else?

It's a step up from 2.3.0 stable, where the Orca would simply crash when attempting to connect to the printer (without clicking the device tab), then on any subsequent boots until the entire config is cleared. Actually, this is the only reason why I've updated to 2.3.1 beta, as I don't tend to run beta software normally.

It's also a minor issue, sending print over wifi works just fine, it's just the device tab that crashes the program and I can load Klipper gui in my browser anyway. Annoying bug, but easy to avoid.
