Text was better than screen-shot, just use Ctrl+E with selected text to apply formatting of console output.

Check whether fingerprint reader is enabled in BIOS.
Maybe it’s integrated with touchpad? Run cat /proc/bus/input/devices |grep -i name

The bios does not mention fingerprint sensor distinctly.

It’s probably Elantech device connected through SPI instead of USB. A driver is being worked on, you can contact the developer and help by testing it:

@vatsal, the driver has been merged and released, have you tried libfprint 1.92?

There’s a F35 version that you could use for testing purposes:
