Ok, do I need to pull reference meshes from the sfm model? or is there any other way I can fix this?

Here's everything I pulled from the SFM model using Crowbar and VTFEdit:

Here's a link to the model I'm trying to import:

Not sure how or where I could upload the actual files I'm trying to use.

I'm trying to import SFM models I downloaded off the Steam Workshop. Whenever I select a file it throws the following error:

------------------------------------------------

Python: Traceback (most recent call last):
File "C:\Users\minec\AppData\Roaming\Blender Foundation\Blender\3.0\scripts\addons\io_scene_valvesource\import_smd.py", line 69, in execute
self.num_files_imported = self.readQC(filepath, False, self.properties.doAnim, self.properties.makeCamera, self.properties.rotMode, outer_qc=True)

shape = qc.ref_mesh.data.shape_keys.key_blocks.get(line[i+1])
AttributeError: 'NoneType' object has no attribute 'data'

Can anyone help me understand what's wrong and how to fix it?
