As a first instance, once the table is open, select say the first 10 columns and sort (from the ribbon) if you get an error, at least one of those columns will be the issue. So refine down.
Alternatively suggest take a copy of the table, delete a field, open the table, repeat for all fields or until you find which ones are causing the issue.
