Looks like you didn't correctly configure the paths required. You can even see the message "Failed to open settings for file at: ...."

You will need to go into the calib.yaml file and update your paths. I realise this is super old but if someone stumbles across it it might help.

# Data path. adjust them!
common:
    image_file: "/home/livox/ws_livox_camera_calib/data/image/0.png"
    pcd_file: "/home/livox/ws_livox_camera_calib/data/pcd/0.pcd"
    result_file: "/home/livox/ws_livox_camera_calib/data/output/extrinsic.txt"

# Camera Parameters. Adjust them!
