OK, I just got off the phone with Apple Support and it was much easier than it seems.

First, shut down. Then reboot, and then immediately hold the Command+R, until you see the progress bar, then release.

Then, you should get a screen that has 4 choices - choose the bottom one - Disk Utility.

Select your HD on left and run "First Aid" (first button in center menu). It should take a few minutes to run.

Once complete, restart from Apple menu, and sign in as normal. Your iCloud Photos should be working.
