Android launcher not working on nexus 4

[AC Question]

My phone was working fine when suddenly today evening the launcher isn't working. The message is 'unfortunately the launcher has stopped' . I'm unable to go to the main menu. Can only access watsapp and call button on my home screen. I have no idea what to do.

In the first instance, try a Soft Reset....Power Off the phone, followed by Restart.
