I am working on MacOS Ventura 13.2.1 using Lightroom CC Version 6.2
I tried to upload a significant number of images onto my desktop but the sync process got stuck leaving a large number unsynced. I tried all the steps I could find in posts dating back to 2017 and even after deleting all the photos I had originally uploaded I am left with a 'syncing 1 image' message on my desktop app (online it appears that all images are synced) which has not gone away after three days. I cannot find what the image is even by filtering 'syncing', clicking on cloud icon, checking sync issues online etc. How do I track down and remove this phantom image that seems to be blocking the rest.
What else is left to try?
