Adafruit NeoPixel Ring - 5050 RGB LED with Raspberry Bullseye

I am trying to get Adafruit NeoPixel Ring - 5050 RGB LED with Integrated Drivers – 12 pixel working with Raspberry Pi 4 and the latest bullseye raspberry pi os 32 bit.

Can anyone advise if they have managed to get this workinf?

I previously used the following configuration which worked fine

sudo pip3 uninstall rpi_ws281x
sudo pip3 install rpi_ws281x
sudo pip3 install adafruit-blinka
sudo apt-get install python-dev git scons swig
git clone GitHub - jgarff/rpi_ws281x: Userspace Raspberry Pi PWM library for WS281X LEDs
cd rpi_ws281x
sudo scons
cd python
sudo python3 build

@reboot sudo python3 /home/pi/rpi_ws281x//python/examples/ &

The pattern starts but then stops.

Can you please advise instuctions/commands to get the neoppixel; ring working
