Installed via Bazaar, clicked Open, nothing happened. Got this when running in terminal.

Running Aurora (KDE based fedora silverblue). Not sure what other info might be helpful here...

Start at src/config/setup.rs:21 and reproduce the failure with the flatpak command from the report, then trace the database initialization and schema or migration that references hotkey.super_key. Done means a clean first run initializes the database and opens without the missing-column panic.
