It looks like you’re using Blinka, both it and libgpiod need to be installed through apt, don’t install libgpiod through pip. You didn’t show your imports, so I don’t know what the module “pin” is from, I’d use board instead, and implicitly specify pin numbers rather than board.SCLK, etc. I also needed to use adafruit_extended_bus rather than busio to get i2c working, it would be a good idea to use this instead because it allows you to specify the device.
