Copper Button recipe makes it impossible by default to return 9 copper ingots from a block of copper, without a 3rd party mod or datapack.

Expected Result
1 Copper Block -> 9 Copper Ingots
Current Result
1 Copper Block -> 1 Copper Button

I used the vanilla recipe patterns when creating the recipes for the new blocks. As a consequence, some vanilla crafting recipes may have been overwritten. I recommend using a mod or datapack that allows you to choose between multiple outputs from the same recipe, such as this one: https://www.curseforge.com/minecraft/mc-mods/polymorph-1-19-port-fabric

Ah I see, my apologies, I did look into polymorph but I only found versions for 1.18.2 Tsym!
