I just noticed that pressing the touchpad down does not trigger any click anymore on my system. It used to work, but I don't know for sure when it stopped working as I've been using an external mouse for like 5 months.
However I did notice that at some point I started getting the following kernel warning on every boot (I believe after a kernel update), which seems related and makes me think it is a kernel regression:
kernel: lenovo_wmi_hotkey_utilities CE6C0974-0407-4F50-88BA-4FC3B6559AD8: probe with driver lenovo_wmi_hotkey_utilities failed with error -5I can still move the mouse with the touchpad, and click with tap-to-click, but still a bit annoying. Any hints appreciated.

I have a similar laptop (14AHP9), and the same kernel log message, but the touchpad clicks work fine. Does:
# libinput debug-eventsshow the clicks?

Hm very strange. Now it registers the clicks "most of the times", just sometimes not. I guess I can't rule out a hardware issue, I'll have to monitor it further. Thanks for trying to help though.

If you can recall approximately when it stopped working, you can check which kernel version it was in the pacman log (substitute "linux" if you are using another kernel).
grep -E "upgraded (linux|linux-[0-9]+)" /var/log/pacman.log*"lenovo_wmi_hotkey_utilities" kernel module is responsible for LED indication on audio mute keys, thus unrelated to this case.
