Blender .dff files won't work importing from game

[Leviathan1998]

I was trying to import modelspc.dff file to Blender from any manhunt level to edit it but I got error:

Python: Traceback (most recent call last):
  File "C:\Users\user\AppData\Roaming\Blender Foundation\Blender\3.1\scripts\addons\DragonFF-master\gui\dff_ot.py", line 278, in execute
    importer = dff_importer.import_dff(
  File "C:\Users\user\AppData\Roaming\Blender Foundation\Blender\3.1\scripts\addons\DragonFF-master\ops\dff_importer.py", line 830, in import_dff
    dff_importer.import_dff(options['file_name'])
  File "C:\Users\user\AppData\Roaming\Blender Foundation\Blender\3.1\scripts\addons\DragonFF-master\ops\dff_importer.py", line 801, in import_dff
    self.import_atomics()
  File "C:\Users\user\AppData\Roaming\Blender Foundation\Blender\3.1\scripts\addons\DragonFF-master\ops\dff_importer.py", line 118, in import_atomics
    mesh = bpy.data.meshes.new(frame.name)
TypeError: BlendDataMeshes.new(): error with argument 1, "name" -  Function.name doesn't support None from string types

location: <unknown location>:-1

When I try import any individual .dff file it opens without problem. Only when I try to import modelspc.dff from game *files example :\Games\Manhunt\levels\prison\pak it gaves me this error.
