How many monitors do you have and how are they set up? I had the same issue - this is how I solved it.
If you have two monitors and monitor 1 is on the right, go to your System Preferences -->Displays-->Arrangement and make sure the menu bar (or whatever it's called) is on the left monitor. Mine was on the right. When I swapped my monitors so it was on the left my Color Correction workspace showed up. See pic below:
