There was a problem opening the obj file with Blender

[name-liang]

 Hello, I converted the .data file into a .obj file and imported it into Blender. I can see the model in the Blender viewport, but it doesn't render the file when I try to render it. Do you know what the problem is?

  like this:

view port

render result

  I confirm that the rendering mode of hair is turned on, please have you encountered such a problem, looking forward to your answer, thank you
