Error about reading the blend file of ShinyBlender dataset

[YiningPeng]

I want to use the *.blend file to create my own dataset. But when I use the bpy lib to read it, there is something wrong with it. The error information is here. I think this problem may be related to the version of blender. Could you tell me the blender version you used? Or could you give me some suggestion? Looking forward to your reply. Thank you so much.
