launcher not showing on the screen

I open the launcher, and it doesn't show on the screen or when I hover over it in my task bar it doesn't show a window. I have tried restarting, reinstalling, but nothing works.

Also this happens in the task manager,

When I expand it, it seems to show 3 open at once.
