Hello There is a wierd problem with running PyQt5 apps with ida 7.2+7.3 running a PyQt5 plugin via the plugin menu(ida_idaapi.IDAPython_ExecScript) runs the plugin but PyQt5 external window (if the app have a external window) wont show. But in the log window you can see the app is runing. But if you use file>>open scriptfile the app runs and show correct. See test plugin. Any idea what the reason could be?
