You're running an early version of Zotero 6 from March. You should install the latest version from the download page and figure out why you haven't received automatic updates in months.
If you're still having trouble after upgrading, provide a Debug ID for a sync attempt that produces the error.

As you suggested above i have downloaded again and installed in my machine. But some of the pages not fetching correct info from Embed Metadata which is previously worked.
EX: (https://www.accessengineeringlibrary.com/content/book/9780071472425/chapter/chapter1) able to save chapter level in translator but unable to save book level (https://www.accessengineeringlibrary.com/content/book/9780071472425) - When i trying to save this page and i am getting "An error occurred saving with Access Engineering. Attempting to save using Embedded Metadata instead."
And also "https://www.accessengineeringlibrary.com/content/calculator/S0071_Basic_Transformer_Calculations' page not even fetching correct item type from Detectweb. This was worked previously but now its looks not showing right info.
Can you please check above and do the needful..
