Volumio errors help

See the screenshot from 15:09,
When I change sources from say playing from my NAS to then trying to stream from wimp or another source volumio airplay selection disappears and I am unable to select it.
It eventually shows backup but when I press play it won’t connect. I have tried various fixes from searching the web but I am unable to resolve it.
It uses wifi on the raspberry pi as Ethernet causes pops and crackles, it is plugged into my amp via USB that utilises an xmos dac.
Any help would be great as I want to stream the likes of wimp and qobuz lossless into my dac from my iOS tablet. ( android is another issue I’ll leave for now)
Thanks

I’ve done an rpi-update, and rebooted. Will see how it holds up tomorrow.
