(macOS 12.5.1) Lightroom classic v11.5 syncing does not finish
I have just started syncing from Lr Classic (v 11.5, Mac OS Monterrey 12.5.1) to Lightroom but it never completes the syncing and continues showing "Syncing 1 photo" in the dialog box, its been like this for 2 days since I
started syncing.

I have read similar threads on this issue and have looked at the sync activity.

For the pending image I cannot find this file in my catalog in LR Classsic and I have not been able to finding in Lightroom in the cloud either but I'm not sure if I can search by file name. Nor do I know what the files are that are in status "downloading" but the number never seems to get less.
Can somebody let me know what is going?
Thanks... it's really doing my head in!!
FYI: a few years ago (maybe 7 or so) I did once try to sync, I think it was Lighhtroom CC or Lightroom mobile at the time, so when I started to sync now it has tried to bring those images across to my current catalog so perhaps these issues are related to back then.
