Sync will not complete - it is stuck saying syncing 53 photos

[MarkH56]

I have been successfully syncing lightroom classic to the cloud storage.

Recently it is showing constantly that it is syncing - it reports permanently syncing 53 photos. New photos and changes are successfully sync'd, but these 53 remain. Main issue is it prevents my Mac from sleeping which is how I have it set.

I can see errors in the diagnostic report, but have no idea what to do to correct these. I have attached the report if anyone knows how to interpret.

thanks
