I don't know the sort order, how can I find row 19641 to fix the address?
What was the original definition of that address_title field? Perhaps varchar(255)? If that's the case, the maximum varchar length for a utf8mb4 database is 192, so you're looking for records in that table that are between 193 and 255 characters in length.
