It is recommended that you perform the following steps to resolve the issue:
Quit Lightroom CC.
Back up all of your local originals.
Caution:
If you have originals on your hard-drive that are not synced to the cloud, it is recommended that you back up your 'Originals' folder before proceeding to the next step.
(Windows)
To back up originals on a Windows computer, do the following:
Navigate to: C:/Users/[user name]/AppData/Local/Adobe/Lightroom CC/Data
Inside the Data folder, look for a folder with a long name made up of random letters and numbers (for example: '1c1fad228a024c1987b5f82737c1b293'). Open this folder to find a folder titled 'originals'.
Copy originals folder to a new location outside the Data parent folder.
