I faced the same issue.
When you are exporting, simply select ‘Compress with GZIP’ rather than ‘Save as file to your computer’.
Both actually produce the same sql file, just that when u select ‘Save as file to your computer’, it doesn’t get fully downloaded. Maybe some download or internet connection problem.
Thanks,
