Using version 3.0.6 for Fabric 1.20.1, crashes as soon as the game starts loading. I have a lot of mods so it's probably clashing with something, but hell if I can tell what. I tried removing other mods that seemed like they might have overlap (e.g. Doggy Talents Next, any of the snow-related mods), but there's no change, meanwhile removing Snowy Spirit fixes the crashing.

My crash log:
crash-2024-08-05_21.04.58-client.txt

I only see an issue from more mcmeta

Removing that causes the following crash, which is pretty clearly Snowy Spirits (and/or Moonlight)-related:

Your moonlight must either be missing or outdated
