Fingerprint LED always on

Hi all, since this morning I am facing a minor issue with the LED of the fingerprint reader of my laptop. It is a Lenovo Thinbook 16 gen 5, and after I woke up my system from standby today, I cannot disable the LED of the fingerprint reader. It is on even when the power is off. There's only one way of turning it off, and it is to unplung and replug it with AC, while power is off. In this case, it will turn from the "problematic" persistent green light (normally meaning that's waiting for input), to a flickering white light (normally triggered when I turn on the laptop) that after 2/3 flickers turns off.

On the packages installed, I had installed fingerprint-GUI from AUR (and its dependencies), then it was not working, and I just kept fprint, so that's what I am using for the fingerprint configuration. After uninstalling fingerprint-GUI, I haven't checked which packages are actually useful or not, among the installed ones.

Has someone any ideas on how to fix this? It is weird since it was not there before.
