At least I'm not alone, can't pinpoint it as well as @Odysseus did but currently running Kubuntu 19.04 - Escribe will download the settings from my device and ultimately freeze after it's done.  Worked in 18.10/.04 etc so could be the same as Odysseus said.  Running from terminal I see some errors with GTK which I'll post below, can't find much more than that though.
 
	First this is output multiple times:
 
Cairo.Surface is leaking, programmer is missing a call to Dispose
	Then this is output multiple times:
 
(EScribe:21591): Gtk-CRITICAL **: 01:05:27.090: IA__gtk_range_set_range: assertion 'min < max' failed
	Those seemed like the most important outputs to me, there's a bunch more if anyone wants/needs the full output.
 
	 
 
	Edit: gonna try downgrading mono
