Yamaha THR30II Roon endpoint?

Anyone familiar with these guitar amps / modellers? Has bluetooth and built in Line 6 G10 wireless guitar receiver (24bit I think). Unexpectedly, Roon saw this device as via a ‘wasapi’ item in Audio devices and played to it even while my laptop was playing bluetooth audio to it. However, it has since disappeared? What’s going on anyone?
