Source model import error

Ever since one of the latest blender updates, trying to import a model that was previously able to be imported is now resulting in this error:

Python: Traceback (most recent call last):
File "C:\Users\user\AppData\Roaming\Blender Foundation\Blender\3.1\scripts\addons\SourceIO-master\source1_operators.py", line 54, in execute
model_container = import_model(mdl_path.open('rb'), vvd_file.open('rb'), vtx_file.open('rb'), self.scale,
File "C:\Users\user\AppData\Roaming\Blender Foundation\Blender\3.1\scripts\addons\SourceIO-master\source1\mdl\import_mdl.py", line 180, in import_model
mesh_data.polygons.foreach_set("use_smooth", np.ones(len(mesh_data.polygons)))
TypeError: couldn't access the py sequence

location: <unknown location>:-1

Not sure what could be causing this and I haven't found any similar errors or solutions to this. Tried reinstalling the add-on a few times but to no avail.
Thanks for any help in advance.

Go to RedXEye's Github and check to see if there has been an update to SourceIO since Blender 3.1 was released. If there hasn't, post your error via the issues link on the page. The Blender 3.1 update may have broken the Add-on code and may need a fix.

Edit - FYI: I have read that there is a new pre-release of Blender Source Tools which kind of indicates that the coding in 3.1 Update is causing problems in that Add-on as well, so, I would suspect it may be the case I outlined above.
