Error code 9 on mac

error code 9. Won’t reload anything. Same message each time ‘Aw, Snap! Something went wrong while displaying this webpage. Error cod 9. Learn more. Reload.’

Downloaded Brave Beta hoping to import my bookmarks, passwards, extensions but it won’t. It only recognises and is syncing with Chrome (which is the browser I downloaded Brave Beta from)

The Brave Browser Version is 123.1.64.113. I’ve tried to update a couple of times and it has been unsuccessful.

Can I recover anything?
