Additional context
Howdy!

I'm trying to get started building a very simplistic mod, but I can't even get it to initialize when I launch MTS. It gives me the error when it starts to load my code.

I have been following the Getting Started guide found here to write this, and copied a lot of my code from existing mod sources. https://github.com/daviscook477/BaseMod/wiki/Starting-Your-Mod

I think I just missed some crucial step which is preventing the .jar file from properly loading.

All my mod is intended to do is modify the existing Defect card, Blizzard, to make it 2-cost, Rare, and channel 2 Frost before it performs the area attack. I copied the Blizzard.java code from the decompiled Slay the Spire directory, the VFX file, and the 1024 portrait. My directory looks like this:
