Just found a fix for this. You need to add libgl1-mesa-glx on line 5 for ..\modules\ImageClassifierService\arm32v7.Dockerfile and add RUN apt update && apt install -y libgl1-mesa-glx on line 9 for ..\modules\SenseHatDisplay\arm32v7.Dockerfile

build your images again, push to the device and happy days :-)

That worked well, thank you
