Lightroom Desktop stuck on syncing 1 image

For as long as I can remember Adobe Lightroom has shown that it is "Syncing 1 Photo". When clicking to view that 1 photo lightroom is unable to display the file that it is stuck on.

I have recently deleted all my storage in an attempt to remove the problematic file. This includes everything in lightroom's deleted folder (there are 0 photos currently synced).
Any ideas what is causing this, and if so is there something I can do to resolve this issue?
On Windows using version 4.2

Would you mind going to https://lightroom.adobe.com and remove the file from your Sync Issues folder and the Deleted items? If that does not help, please checkout the steps below:
Switch to the Square Grid view which displays photos as equal-sized thumbnails along with their flag status, sync status, and rating.
a) Delete the selected photos by choosing the Edit > Delete option and then add the photos in Lightroom CC again.
b) Apply a flag or a star rating to selected photos.
c) The syncing issue should now be resolved. To check the sync status, click the cloud icon at the upper-right corner.
Let us know how it goes.
Thanks,
