Keyboard on Asus Laptop (M3402RA) not working after plugging in external keyboard

I have had this laptop (Asus Vivobook S14 M3402RA) for about a month now and I installed Linux on it without any major issues. However, a few days ago, when I plugged in an external keyboard, the laptop’s built-in keyboard became unresponsive. I found that the keyboard was unresponsive even after unplugging the external one.

I tried reinstalling my system and I had high hopes as the keyboard worked in the BIOS menu. Unfortunately, this was not the case when the desktop environment loaded up. I tried this process with the following desktop environments (the keyboard did not function on either one): i3, hyprland, kde, gnome, lxde. I have tried a rolling-release distro (arch linux) and a stable one (linux mint) but the keyboard did not work on either.

I would like to note that the touchpad works everywhere, as do the Fn keys.

The problem is very similar to the one described in this post: Keyboard not working in ASUS Vivobook S 15 (2022) and Kubuntu 22.04

I have also tried the solutions in this post, but they did not work: https://askubuntu.com/questions/1360683/keyboard-not-working-after-shutdown-asus-zenbook-13-oled-um325s/1363587#1363587

Any help would be greatly appreciated!
