Ubuntu – I cannot open system settings in ubuntu 17.10

system-settings

When I chose settings from taskbar menu nothings happened. I have been working a while ago, last think that I did was removing ~/.pulse directory and run pulseaudio -k and pulseaudio --start (from this thred – No sound after update to ubuntu 17.10).

I can see error in logs when I click setting button (journalctl /usr/bin/gnome-shell -f -o cat):

JS ERROR: TypeError: app is null
