RDM Linux 2026.2.0.6 - NullReferenceException when attempting to quit application

Hello,

On my Arch system, whenever I try to quit RDM from the tray icon, I get the following exception:

NullReferenceException - Object reference not set to an instance of an object.

   at Client.Windows.MainWindow.SaveLayout()
   at Devolutions.RemoteDesktopManager.Managers.ActionManager.ForceClose(Boolean exit, Boolean saveOpenedConnections)
   at Devolutions.RemoteDesktopManager.Managers.ActionManager.QuitApplication(Boolean saveOpenedConnections)
   at Client.Menus.TrayiconMenu.OnQuit(Object sender, EventArgs args)
   at InvokeStub_EventHandler.Invoke(Object, Span`1)
   at System.Reflection.MethodBaseInvoker.InvokeWithFewArgs(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)

When I try to quit application from the menu (File / Quit) I get the following exception:

NullReferenceException - Object reference not set to an instance of an object.

In both cases, the application window remains open and the application will not end.

This error manifests only with the current version - 2026.2.0.6.

Application has been installed from the AUR package
