    error: 'iriunwebcam-bin-2.2-3-any.pkg.tar.zst': no se pudo encontrar o leer el paquete

From you path it seems you are in modprobe.d folder - which is probably not where you build the package.

You need to be in the same folder as the package to install when using pacman -U or your need to specify the full path to the packages.
