Google Drive does not work offline, even if the database file was “Made available offline”.
As a workaround, you can open Google Drive app, select your database, press “Open In” and then “Copy to KeePassium”. This will create a local in-app copy of the database, that will not be synchronized with Google Drive. To share any offline changes, you will need to export the database back to Google Drive.
