Rpi 5 8 GB hailo8 (26 TOPS) intance segmentation error

Hello everyone,
I converted the yolov5n_seg.onnx file into yolov5n_seg.hef format using hailomz. However, when I tested it on the instance_segmentation.py file found in the rpi5 examples, I encountered the following error:

Segmentation Fault

Can you help me?
Thanks!
