PS audio Directstream Junior locked

Hello,
I have been listening to Spotify Connect via ethernet into a PS Audio Directstream Junior with a PrimaLuna Prologue Premium Integrated without issue, but today I can no longer change the gain or navigate the menus. It boots up fine but appears to be frozen. I reinstalled Snowmass without resolution. I also removed the ethernet cable and rebooted, but it's still locked. Spotify will still stream through the bridge at a lower gain and USB no longer works.

Has anyone run into this issue or know how to resolve?

Thanks!
