Thanks for the tip. Edge was the default browser, but changing to Chrome (which was also on the machine) had no effect to Roon freezing when trying to display album artwork. I tried to install an old version of Roon but forgot that Roon is setup in my network to force upgrades so I ended up back on the latest version, which ended up freezing again.
So I’m back to where I began. RoonBridge does work since it doesn’t rely on an interface. But the interface was kinda the point, especially on this machine in my house.
