According to the design, we should add the error and reason if wallet cannot open the DB OR if DB is broken: https://zpl.io/2GGj4jm But currently, for getting this info we should know the password for wallet.db and there is a problem now, because according to the logic user provides the password only after select and migrate the DB. So we need to find the solution on how to check the wallet.db for errors without entering password
