Perpetual Sync

LR updated and been stuck in perpetual sync between MacBook Pro and cloud. It seems to think there's 85 items that need syncing. Plus unable to add additional photos. All software is up to date, I've removed all sync problems from the Lightroom.adobe.com. Signed out all accounts. Uninstalled and re installed. Also, LR will not close. I have to force quite to get it to close. As it stands it's unusable.

any suggestions would be helpful, thank you in advance.
