Issues with fingerprint reader

Hello, I'd like to enable finger print login for my laptop.

I've followed the wiki article for fprint and installed fprintd and libfprint-elanmoc2-newdrvs (I already had imagemagick installed). The output of

yay -Q | grep -i fprint

is:

fprintd 1.94.2-2
libfprint-elanmoc2-newdrvs-git 1.94.0+11+g32b8a2d-1

I installed the latter library because from lsusb I can see that I have an ELAN device with ID 0c00, which is not in the supported devices list, but is however mentioned in the wiki article in the installation section.

Now, when I try to enroll a fingerprint, I get different errors, seemingly at random.

I have GNOME and GDM installed, so I tried enrolling fingerprints from the GNOME settings panel. Sometimes, I reach the end of the enrollment process and get the "Problem Reading Device" error. Other times, for a brief moment, the operation succeeds and then errors out, allowing me to save the fingerprint by clicking on "Done" in the pop-up window.

I have dumped my system journal after a reboot and followed the same procedure to show the errors fprintd encounters:

I have also tried enrolling fingerprints manually with fprintd-enroll. When I do that, I almost always encounter this error by the end of the procedure:

I've looked around online but cannot find this same issue elsewhere, so maybe you'll be able to help me. Below, the output of my neofetch:

Re: Issues with fingerprint reader

I am getting the same error as @ZeroKun265 , except that there's nothing in the journal. I also have the ELAN ARM-M4. The enrollment hangs at enroll-stage-passed.
