I'm not sure any part of fingerprint reading goes through libinput so
let's start with libfprint/fprintd.

Title:
  Fingerprint reader gets randomly dissabled

Status in fprintd package in Ubuntu:
  New
Status in libfprint package in Ubuntu:
  New

Bug description:
  I own the DELL 16" 4650 which is one of Canonical's supported laptops.
  Came preinstalled with Ubuntu.

  The fingerprint reader does not work as expected. After sleeps,
  reboots, or updates (or whatever else triggers it, I don't know), the
  fingerprint reading gets disabled. I have to re-scan my finger, it
  tells me that this finger reading already exists, then I redo the
  scanning again, and then it takes it in.

  But after a couple of sleeps, or reboots, usually multiple times a
  day, the same thing happens again, it gets disabled all by itself. The
  frprint command line utility also says that no finger has been indexed
  in its db (while it has, a lot of times so far).

  I have set it up both via gnome's fingerprint ui, and via the pam-
  auth-whatever terminal utility.

  The same bug happens on CachyOS btw, installed in parallel on the same
  computer, not just on ubuntu.

  For a Canonical-authorized laptop, both the touchpad and the
  fingerprint experience sucks. In fact, I bought this laptop
  specifically because you say on your website that these are authorized
  laptops.

  More info about my exact hardware via ubuntu-apport can be found on my
  touchpad bug report: bug #2122154

  Another issue is that the fingerprint reading on gdm during login does
  NOT unlock the gnome keyring, so when launching Chrome/chromium it
  asks for a password. Super annoying.
