First step is to reset LrC preferences file as detailed in the below article. Place a copy of the current Preferences file on your desktop so it can be easily restored if the issue persists.

I have tried this but, the problem is persisting.  Edit in Photoshop is greyed out.

Todd, thank you so much! Resetting the Preferences seems to have solved the problem.
