error import

[saibai]

I can't import ply files, it always gives me this error, on Blender 6.5.1 and MacBookPro M2

Python: Traceback (most recent call last):
File "/Library/Application Support/Blender/3.6/scripts/addons/blender-addon/init.py", line 66, in execute
log_opacities = np.asarray(plydata.elements[0]["opacity"])[..., np.newaxis]
File "Library/Application Support/Blender/3.6/scripts/addons/blender-addon/plyfile.py", line 715, in getitem
return self.data[key]
ValueError: no field of name opacity

how can I solve it?
Grazie
