I have exactly the same issue. Have tried everything but nothing works. Hoping they fix the bug asap

No progress yet. My shared library on beta.icloud.com is empty. Still not syncing. But the personal library says 4617 photos, 54 videos and 1 other item that I don’t seem to understand… i feel this other item might be preventing the sync but I can’t seem to find it…

Now i have deleted all photos from personal library. There are no photos in shared library as well. Hope everything syncs now
