I followed the included direction packets and all the directions I have found online and I can’t seem to communicate with the camera’s motor to focus. The raspi OS, libraries, kernel, ArduCAM git folders are up to date. The settings match recommended. The boot file has been edited as recommended. This is the 3rd ArduCAM unit I’ve bought and I get the same issue with all. Please help!!
I can preview a clean image when I issue command: libcamera-still -t 0 however when I try to use one of the Python or C files on the github (RaspberryPi/Motorized_Focus_Camera/python at master · ArduCAM/RaspberryPi · GitHub) I get errors. For example:

Maybe an i2C communication issue? Also have gotten Segmentation Fault errors. What is the Mismatch between Unicam and CamHelper error message? If there are any ideas on how to fix this, please let me know.
