Can't gpioInitialise on a Pi 400

I'm aware this library is still in beta for all Pi 4 Model B devices. I just wanted to share that it works fine on my normal Pi 4 B (https://www.adafruit.com/product/4292), but not on my Pi 400 (https://www.amazon.com/dp/B08RMJR4CK/ref=twister_B08RMNBYBK). Here is the error message I get on a Pi 400.

If there is so way to use this library on a Pi 400, I'd love to get it figured out. I'll have students test it in class today, so we'll have 20 more Pi 400 test users soon. :) Let me know if there is anything you want me to try. Thanks!

Note: for now we'll just use your onoff library on the Pi 400, but we eventually need features that are only available in your pigpio library.

What version of the pigpio C library is installed? Please check with the following command:

pigpiod -v

If the version is less than 74, please update to the latest version of the pigpio C library.
Installation instructions can be found here.

Yep, you nailed it. The default version of pigpiod is 71 right now. That does not work on the Pi 400. I did the update and got 79, then it worked fine. Thanks!

For my notes to remember what I did...
ref

pigpiod -v
(was 71)

sudo killall pigpiod
wget https://github.com/joan2937/pigpio/archive/master.zip
unzip master.zip
cd pigpio-master/
make
sudo make install
sudo pigpiod
(actually what I did was 'sudo reboot', but sudo pigpiod should've been plenty)

pigpiod -v
(now 79)
