Inserting item into specific slot crashes game 1.18

[awesomedude3595]

I have been trying to create a custom GUI that can use custom crafting recipes. The crafting part doesn't work I assume that this is because of this:

public RecipeType<?> getType() {
        return RecipeType.SMITHING;
    }

In the common/crafting/ModUpgradeRecipe, however you cannot create a custom RecpeType because there is no forgeRegistry for it. Also whenever I put any item in the 2nd slot the game crashes, I didn't have that issue until and added the matter_essence_converter.json recipe file. Pls help me fix these issues. Here is git repo https://github.com/Awesomedude3595/1.18.1-Handheld-Inventions

you can just use the vanilla registry, RecipeType.register

I have added a RegistryType and now the game no longer crashes when you put something in slot 2. When I put the items in it does not put anything in the result slot. Therefore I presume that my recipe is not working or loading.
