Fingerprint doesn't work on Sony 1 VI (XQ-EC72)

[Gireev]

Describe the bug

I am unable to unlock the database using the fingerprint feature.

To Reproduce

Steps to reproduce the behavior:

1. Open KeepassDX
2. The fingerprint button displays "unavailable."
3. Tap the "unavailable" button.
4. Toasts appears: "Type password and then click the button."
5. Begin typing the password.
6. A toast notification appears: "System error (internal Keystore code: 4, message: system/security..."

Expected behavior

The database should unlock using the fingerprint feature.

KeePass Database

• Created with: [Windows KeePassXC 2.7.*]
• Location: [/storage/emulated/0/Download/Keepass/databasename]

KeePassDX:

• Version: [4.0.8]
• Build: [Free]
• Language: [English]

Android:

• Device: [Sony Xperia 1 VI XQ-EC72]
• Version: [14]
• Phone Firmware: [69.0.A.2.38]

Additional info
I went to "Device Unlocking" and deleted the encryption keys, then reinstalled the app. I am unsure if this is a bug with KeePass or an issue with the phone's software. It start to happen after some software updates and updates of Keepass. Other apps which using fingerprint works fines.

It seems that some systems break their keystore after an update. Try rebooting your phone or contact SONY.
