Hmm this almost looks like the Patcher was trying to open a patch before the libraries were loaded - fixed when 1.1.0 comes out.

you can’t press Live? could the Ksoloti Core be disconnected? what patcher version are you using? use 1.0.12 for the current stable release

But it doesn’t work again, even after pressing “sync libraries”. Java’s mistakes repeat.

That’s Arch Linux. Is it even supported? Did you to the equivalent of [setting udev rules](https://ksoloti.github.io/3-install.html#linux_permissions)?
