I located the file and made the same edit, deleted temp folder, and started SF. No success. I'm on 13.7 Ventura, FWIW.

You either messed up the edit outright, messed up the indentation, or saved the file with a different extension.
Download the StreamFab for windows installer and extract (not run, extract) the file. Find the script and copy it over your original.
I would say save some bandwidth and download my MOD and copy the orig.amazon_get_seasons_info.py over your amazon_get_seasons_info.py but with StreamFab installer, the file is already named properly.
I am not trying to be a dick and suggest you can't rename a file properly but i don't know your level of proficiency. You are using a Mac after all :p
