Hey, I'm facing the exact same issue, on the same device i.e. Poco F6. It is running Android 15 (Crdroid 11.5).
Also I've tested multiple other applications that use Biometric Authentication, so it does not seem to be an issue with the ROM.

These are the crash logs I have:

Same error on PocoF6 on Derpfest rom:

Log:

EDIT: It seems at least for me, that deleting fingerprints, and recreate them works.

Actually, the crash occurs when there are two or more fingerprints registered. It works fine with one.

I deleted all the Biometrics and registered a new one and now it seems to work!

I have the same issue too and the workaround does not work. Deleted and recreated fingerprints, reinstalled Bitwarden even, but to no avail.

This fixed the issue for me on Poco X6 Pro with an unofficial lineageos build
