Zotero 7:File synchronization error
                    Error ID: 1264209187; When Zotero is opened, it automatically starts synchronizing. The synchronization continues until the upper right corner shows that there is 1 remaining amount and the remaining amount no longer decreases. Then it continues to synchronize until an error occurs.

            AbeJellinekYou're on a somewhat outdated version of Zotero. Try updating to 7.0.24 first and see if that fixes it.
