player animator crashing when loading minecraft

I've been trying to figure out why Minecraft has been crashing from player animator. Minecraft will load all the way but before loading the main menu it crashes with the error java.lang.NullPointerException: Cannot invoke "com.google.gson.JsonElement.getAsJsonObject()" because the return value of "com.google.gson.JsonObject.get(String)" is null

Idk if im just being dumb and this is a simple fix but I can not figure it out for the life of me. I've tried rebuilding the code and that didn't work. I do have geckolib installed so maybe that has something to do with it but I don't think so.
