wondering if its a version mismatch issue?

It could be a version mismatch error. I'd guess newer watches might have different formats, too, and I'm not sure what state of the art is for parsing all these files...

I think filter_files is a generator, and it hasn't gotten past any files. If you're running this locally, you might edit ~/projects/strava_calendar/strava_calendar/data.py:171 with

try: 
  strava_file = StravaFile(data)
except:
  print(f"{fname} failed!")
  continue

and see if you get most of your data.
