Observed behaviour
What is supposed to happen:
- The app should handle not seeing a key and either show a prompt for the user to insert said key or show an error saying no key is detected.
- The app stays frozen, no alternative login is possible forcing app restart (sometimes restarting shows a typical can't connect error instead of the login screen as well)
Reproduction steps
- Use a flatpak/flathub version of app.fluxer.Fluxer
- Grant socket=pcsc and --talk-name=org.freedesktop.secrets using flatseal or flatpak cmd
- Attempt to log in using a passkey without inserting a key first
- RESULT REACHED: screen locks up / goes gray but no window to use a passkey / error is shown
