I am having the same issue for about a week now and I use the HOME page all the time, it's very useful. I installed the update for PS today from CC Desktop hoping that would fix the problem, but still there?
I'm a little concerned about re-setting the preferences tbh. I have copied the folder (as suggested in your link above) but if that fixes the issue, how to we then put all the other stuff back? I have a lot of preferences saved.
