Hi there, I'm using GrapheneOS on a Pixel 8 (codename shiba) and I'm looking to migrate from Bitwarden to KeePassXC and KeePassDX on mobile.

I'm running into a problem that so far I could not solve: the software seemingly lets me set up the biometric (and device pin) unlock device, but when I try to unlock my database with it, it seems to have forgotten it. Here's what happens step by step:

Setting up:

On the Unlock screen I enter my correct password and on the bottom left I click "Device unlock link".
A fingerprint prompt opens reading "KeePassDX Link to device unlocking - You still need to remember your vault main credential if you use device unlock recognition". I touch the fingerprint sensor. It accepts.
A toast appears briefly: "AdvancedUnlockManager not initialized".
To test it, I lock the database again, and I'm back on the Unlock screen
Now it offers "Unlock" with the fingerprint icon next to it, but when I give it the fingerprint, it gives another toast saying "Cipher not initialized".

So far I haven't found out anything about this on the web, so maybe it is unique to GrapheneOS or something on my device? This is my main profile where all this is happening. Maybe any of this rings any bells. Thanks in advance for your thoughts on this.

According to logcat in the last step this happens
