"tuple index out of range" Blender Plugin Error

[TechnoSchnauzer]

I tried to import a dumped model and got this error.

Python: Traceback (most recent call last):
  File "C:\Users\diane\AppData\Roaming\Blender Foundation\Blender\3.5\scripts\addons\blender_3dmigoto_gimi.py", line 2133, in execute
    import_3dmigoto(self, context, paths, **keywords)
  File "C:\Users\diane\AppData\Roaming\Blender Foundation\Blender\3.5\scripts\addons\blender_3dmigoto_gimi.py", line 945, in import_3dmigoto
    obj.append(import_3dmigoto_vb_ib(operator, context, [p], **kwargs))
  File "C:\Users\diane\AppData\Roaming\Blender Foundation\Blender\3.5\scripts\addons\blender_3dmigoto_gimi.py", line 977, in import_3dmigoto_vb_ib

    if len(data[0]) == 4:
IndexError: tuple index out of range

If the model I was trying to dump's files are important here they are: hash.json Pointed_Ear_DogHead-ib=6da32782.txt Pointed_Ear_DogHead-vb0=4ccbe27c.txt
