I know you're running Moode on a Raspberry Pi what else would it be 
What device are you running BubbleDS on?
Did you try a lower Qobuz resolution?
For BubbleUPnP to work enable the UPnP Openhome option in Moode's UPnP options...
... this works for me, under Configure > Audio > UPnP/DLNA > UPnP Config > [Edit] button
In BubbleUPnP you configure your Qobuz account in Settings > Local and Cloud > Qobuz > Enable (tick the box) > Account (enter your account details).
To stream to Moode you pick the "Moode UPNP" renderer in the Now Playing screen, Select the Local and cloud library (in the library screen) > Qobuz, browse/play your Qobuz library in BubbleUPnP and it should go to mpd's UPnP renderer.
You can also choose Qobuz resolution in BubbleUPnP under Settings > Local and Cloud > Qobuz > Wifi/Eth audio quality
