So, restarting didn't work, downgrading to 4.0.4 worked (sorta).
I can login using the bunker flow and Citrine, it pops up an error about "mute kind something something" but eventually it works.

But even 4.0.4 isn't letting me login with a standard nostrconnect flow which is the only option in some clients out here.

With 4.0.4 I can also log in to Amethyst.
IMO there's definitely a regression here, or rather several, as Amber used to work even with nostrconnect flows for me. Unfortunately I don't have another device to test this. What do you want to do here? Happy to drop this as I'm not even really using Nostr that much anymore, but if you want me to do anything to help you troubleshoot this, happy to DM you logs, grant you remote access or do any other tests you require.
