I'm trying to run the examples/rgb_display_minipitftstats.py and I get the following error:

Traceback (most recent call last):
  File "/home/pi/src/picam3-minipitft/button.py", line 11, in <module>

lgpio.error: 'GPIO busy'

I was able to get the requirements loaded with the following:

sudo pip3 install --break-system-packages adafruit-circuitpython-rgb-display
sudo pip3 install --break-system-packages spidev
sudo pip3 install --break-system-packages --upgrade adafruit-python-shell click setuptools
wget https://raw.githubusercontent.com/adafruit/Raspberry-Pi-Installer-Scripts/master/libgpiod.py
sudo python3 libgpiod.py

Are there any updates or instructions to get the minipitft board working with a Pi5/Bookworm? This does work on a Pi4/Bookworm.

I was also getting:
lgpio.error: 'GPIO busy'
for a different example.

I had to "disable them from Operating System" using this guide:
https://learn.adafruit.com/circuitpython-on-raspberrypi-linux/spi-sensors-devices#reassigning-or-disabling-the-spi-chip-enable-lines-3097985

sudo -E env PATH=$PATH python3 raspi-spi-reassign.py --ce0=disabled --ce1=disabled

Thanks, @mores, I've followed those instructions but I'm getting the following error now:
