Lost keyboard and touchpad after latest update

Hi,
I have a Dell e7470 running EndeavorOS Xfce. I’ve frequently updated the system using pacman -Syu. However, when I did such update tonight, the system booted up successfully but keyboard and touchpad did not work at all so I got stuck at the login screen. I tried to boot both the LTS and mainline kernels but got the same problem. Please help!

Thank you.
