Help! My laptop auto writes * character

I just opened my laptop laptop and when I try to write something in web browser, terminal or anywhere I can't even write anything because the laptop itself writes * character and it goes on writing that. What is happening?

Gremlins, Poltergeists… your house is clearly haunted.

Less superstitionally, this is typically some "keyboard" device generating spurious input.
Webcams and BT headphones often have such.

sudo libinput debug-events

will reveal the device,

sudo libinput list-devices

what that is and then we'll need to find a way to stunt it.

The problem persists even in a live Arch boot. I guess this is a hardware problem.

I'm dead sure it's a "hardware problem", did you check libinput for which device actually generates the input?
