@AhnFire did you try setting it up manually?
I also ran into this issue.
Seems the power button works for turning on and off for now though.
Did however run into a situation where I shutdown from within Pi OS and the fan kept running for way too long, had to turn it back on and press and hold the power button for it to turn off.
I’m trying to remember where I was with this. You are referring to the Argon1.sh setup script, right? I had tried something very funny and it worked. I am not sure why. I’ll list what I did.
Bookworm 64-bit lite - Did not work. Basically crashed on that screen, could not select go or stop.
Bookworm 32-bit (with desktop) - Worked in terminal.
Bookworm 64-bit (with desktop) - Worked in terminal.
Bookworm 64-bit lite - Worked! I have no idea why (did they fix the script?)
That leads me to where I am now. For other compatibility reasons, I am now on Bullseye 64-bit lite (the prior debian/Raspberry Pi version aka Legacy). It works fine there. So now I am sorted.
I hope my nonsensical steps above help you get it installed and configured.
