Try to re-enroll it again. The hardware appears to be detected, but enrolling a fingerprint is a tricky endeavor for some fingers. Mine for example have a tough time if too oily or too dry even.
Fingerprint reader is working on KDE Neon. The firmware updated through Discover. After a couple of re-boots, I had to run sudo pam-auth-update and now itās working

What I hope may be my definitive contribution to this thread. Same setup, Windows11 and Ubuntu 23.10. Short version: I have finger prints working for login on both OSs with a specific limit.
The fingerprint reader works fine in Windows for login and fine in Ubuntu for login and sudo. What does NOT work is trying to use the same finger! I have one for each and that has been consistent and functional for a week.
I infer that, yes, the fp hardware must save a copy of each finger. It is a security violation (I conclude) to try and allow the same finger to be valid on all systems. When I think of siloāing the fpās in the reader that seems to make sense.
Whatever else the case, I actually have fingerprint login on both my hosts. Pleased

I can confirm that using a different finger in each OS has worked for me as well, dual-booting. I donāt have things set up currently to boot three or more OSes, but I would assume that using a unique finger for each OS would work. So, we are limited to 10 OSes. Iām not sure if I find that to be an acceptable limitation (joking!).

Awesome to hear this! 
This is absolutely helpful, thank you!
For those still having issues, it seems that everything has been fixed upstream as stated here :
Still this version has to be packaged by the distros (hopefully real soon for fedora)
On testing, it is already available on Fedora 39 as of today 
Niiiice!
Iām on Fedora 40, and when I used distro-sync, the fwupdit put me on showed no available updates when following the steps in this post. After re-upgrading it back to the latest (with the lvfs-testing repo enabled), I was able to install the firmware update no problem. Iām guessing based on the above posts this is expected, but just in case it helps anyoneā¦
Thanks for the guide, I also had to reboot a bunch of times before it finally took my fingerprint, but then every time I try to add another it says the device was busy and hangs. Then it wonāt work to authenticate. Itās very odd. Any ideas?
EDIT: it just started working but does seem to time-out when trying to add a second fingerprint. First one works, though! Maybe thatās all I can expect for now?
Iāve followed this guide closely (twice) and Iām still getting an error on Ubuntu 24.04, any help?
Firmware guide has been updated, please use this.
