Hello, I am having the exact same issue using Raspberry Pi Model 4 B.
using any of the FocuserExample.py or AutofocusExample.py gives me the same error.

configuration:
Raspberry pi 4 b 8Gb
Raspian buster
Camera was purchased and delivered Dec 2, 2020.

camera is enabled in config
i2c is enabled in config.
raspivid and raspistill produce images and video.
Using VNC to view desktop

Will be seeking refund if not rectified.
