I may be able to help but my machine is GTR5 5900HX. The biometric fingerprint sensor is;

EgisTec Touch Fingerprint Sensor
Driver date: 20202/06/15
Version: 3.6.2.1
Hardware ID: USB\VID_1C7A&PID_0577&REV_1041

What's inside your computer?

The fingerprint's device is LighTuning Technology Inc. EgisTec EH575.
Thank you for your response.

EgisTec doesn't seem to have Linux drivers

Do you have libfprint installed?

I have GTR5 5900HX. The machine doesn't have same version of the fingerprint sensor on your machine but this is what I did.  Was I lucky or it's the right thing to do?  I'll keep working on/off on a solution. Cheers!

Enabling Fingerprint Sensor under Ubuntu... The fingerprint Sensor wasn't activated by default after installing Ubuntu. I have installed some Office Apps and Printer drivers... I then installed libfprint 1.94 and did the following steps. Today, the fingerprint sensor works but on and off... If I find something working 100% of the time, I will post it!

Regards,

1) Utilities -> Terminal
2) sudo pam-auth-update
3) Highlight the “Fingerprint authentication” item in the list and press the space bar/key to enable it.
4) Press Tab to highlight the “<Ok>” option and press Enter.
5) Restart your computer to apply this change.
6) To enable Fingerprint login for your user account;
   -> Settings -> Users -> Unlock
7) Click on the “Fingerprint login” button for your account.
8) Enroll your fingerprint(s).

Yes I have libfprint installed, but after the setup it didn't work.
I also uninstalled and reinstalled it but nothing happened.
Egistec didn't reply my email too.
It's a shame...

Thank you for your help.

As I said, I have part of it working but it's really working on/off. I will keep experimenting and will let you know if I find something. Let me know if you find something. Cheers!

Linux drivers have an real issue recording then verifying the recorded print.  This is mostly a software issue because the reader has a rather poor resolution.  So the software has to be more forgiving than it is right now to have a higher success rate.  If you talk to the libfprint developers on GitHub they discuss this issue in detail.  The real solution is for better readers to be available, that have a high resolution capture, and then the matching logic changed in due course.  The interesting thing is, Windows process uses more a touch approach, but the Linux approach is more of a swipe approach, when using the same hardware.  I often forget or mix up the touch vs. the swipe and that hurts the success rate... when either actually work at all, even on Windows 11 Pro, very random working or not working... what a PITA.
