I'm using 3.1.0, only thing I can't export are models as smd in 2.9+, animations export fine, If I go back to 2.8 models also export fine.

If you are trying to export using 2.83, then why is Blender Source tools in a folder for 2.91

"C:\Users\*****\AppData\Roaming\Blender Foundation\Blender\2.91\scripts\addons\io_scene_valvesource\export_smd.py", line 207, in execute

Uuuh, I searched on the steam page for the lastest update and all I could see was 2.83, completely my fault sorry, I'm using 2.91.

Everytime I try to export a model as SMD i get this error, doesn't happen with older versions eg 2.8:
Python: Traceback (most recent call last):
