Failed to restart the panel

I have lost access to system tray and need help to restore it. I deleted several apps in an attempt to fix audio problems, one of those apps may have been XFCE pulse audio related. Not sure if I can view the history of add/remove because I restored a previous version of system backup, without backing up current.
I have tried layout switcher and panel profiles but the task bar is not visible.
I cannot open panel app either - failed to open preferences dialouge or failed to restart the panel - GDbus.error:org.freedesktop.dbus.error.serviceunknown: the name is not activatable
I have updated all apps.
Any solutions?

Sorry for the late reply. Yes that should fix it. I am happy you found a fix. It basically crashed. It needs a sort of “reboot” of the panel.
