If the applications stoped showing in Unity Dash than you should first kill this daemon:

pkill -f unity-applications-daemon

The next step go to your /home directory and press CTRL+H to reveal hidden files. Than search for .cache folder open it and delete software-center catalog.

Afterwards restart the applications daemon:

/usr/lib/unity-lens-applications/unity-applications-daemon

If you still don't have anything in the Dash than press ALT+F2 (to bring up run command dialog) type there:

unity --replace

and run that command. If that didn't do the trick try rebooting computer.
