Hello, I am using pgadmin since several years now and had no real issues so far. Actually, this has changed under Kubuntu 23.04. If I am trying to start pgadmin4, the splash screen comes up and after 90s a "Fatal Error" windows appears with the message "The pgAdmin4 server could not be contated". The content lists my environmental variables, see end of the mail. From my point of view there are no issues. If I start pgadmin from console I get: --snip-- joachim@Theophila:/usr/pgadmin4/bin$ ./pgadmin4 (pgadmin4:6329): Gtk-WARNING**: 10:29:38.901: Theme parsing error: gtk.css:1649:16: '-gtk-icon-size' is not a valid property name (pgadmin4:6329): Gtk-WARNING**: 10:29:38.901: Theme parsing error: gtk.css:1652:16: '-gtk-icon-size' is not a valid property name [6329:6329:0530/102939.012366:ERROR:object_proxy.cc(623)] Failed to call method: org.kde.KWallet.isEnabled: object_path= /modules/kwalletd5: org.freedesk top.DBus.Error.NoReply: Message recipient disconnected from message bus without replying [6329:6329:0530/102939.012382:ERROR:kwallet_dbus.cc(100)] Error contacting kwalletd5 (isEnabled) [6329:6329:0530/102939.012635:ERROR:object_proxy.cc(623)] Failed to call method: org.kde.KLauncher.start_service_by_desktop_name: object_path= /KLauncher : org.freedesktop.DBus.Error.ServiceUnknown: The name org.kde.klauncher was not provided by any .service files [6329:6329:0530/102939.012641:ERROR:kwallet_dbus.cc(72)] Error contacting klauncher to start kwalletd5 [6329:6329:0530/102939.092640:ERROR:object_proxy.cc(623)] Failed to call method: org.kde.KWallet.close: object_path= /modules/kwalletd5: org.freedesktop.

But kwallet is not active, it is disabled. Do you have any advice, how to solve the issue that pgadmin is trying to contact kwallet even if it is not intended to do so?
