Hello, this issue is likely caused by running out of disk space during the statistics building process, which leads to the freeze. If the program freezes while building stats, it can corrupt the database.
Could you please close Hand2Note and delete the 'reports' and 'statistics' folders from the directory where your database is stored? it's located here: C:\Users\user\AppData\Roaming\Hand2Note/Databases\Hand2Note
Then launch Hand2Note and click on 'Import- > Clean & Rebuild Statistics.'
