AttributeError: 'NoneType' object has no attribute 'bones'

After completing the Windows compilation, I got the .bvh file using the CLI, and then utilized Blender along with MPFB and blender_bvh_plugin.py.

I got an error:
Python: Traceback (most recent call last):
File "C:\Users\able1\Desktop\SAM3DBody-cpp-main_WIN_SRC\75.blend\blender_bvh_plugin.py", line 577, in execute
File "C:\Users\able1\Desktop\SAM3DBody-cpp-main_WIN_SRC\75.blend\blender_bvh_plugin.py", line 557, in copySkeletonConstraints
AttributeError: 'NoneType' object has no attribute 'bones'

CLI：
offline_sam_3dbody_render.exe --onnx-dir ./onnx --gguf ./onnx/pipeline.gguf --yolo ./onnx/yolo.onnx --from 100.mp4 --bvh ./p.bvh

windows build: #2
