Ok, for me it’s fixed. When not in fullscreen, I simply resized the Roon application window slightly, and voilà, no more freezes when clicking on an artist name.
It must be related to some screen resolution or window size variable that wasn’t set properly, and by resizing Roon that variable was reset.
In your case, I would try to temporarily change the resolution of my screen, go full screen and see if the fixes it.
