Redhat Enterprise 9 + Flatpack + Unable to load SQL Lite datasource. The saved master key is invalid.

Dear Member,
recently I've installed RDM to my RHEL 9 workstation via Flatpack.

When I start the app says:
Unable to load SQL Lite datasource. The saved master key is invalid.
and when I close the error message:

DllNotFoundException - Unable to load shared library 'libWebView.so' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: liblibWebView.so: cannot open shared object file: No such file or directory

   at Client.Views.Dashboard.DashboardSecondaryView.LoadConnectionViews(IConnectionSource source)
   at Client.Views.Embedded.EmbeddedDashboardView.RefreshDashboard(IConnectionSource source)
   at Devolutions.RemoteDesktopManager.Managers.EmbeddedViewManager.RefreshDashboard(IConnectionSource source)
   at Devolutions.RemoteDesktopManager.Managers.EmbeddedViewManager.ConnectionDidChange(IConnectionSource source)
   at Client.Views.Navigation.NavigationConnectionTreeView.OnSelectionChange(IConnectionSource source)
   at Client.Views.Controls.ConnectionTreeView.OnTreeSelectionChanged(Object sender, EventArgs args)

I close this too andI try to add a new Datasource but app immediately quits.

Anyone found some solution or workaround to get this thing works on RHEL9?
