Hi, I have a problem. On the forge website, you have posted a version of this that works with fabric for 1.16.5, but the crafting recipes listed here don't seem to work. Is there any reason for this?

Use a mod like REI to confirm the recipes are being loaded. The only incorrect recipe on the README page is the Netherite one. If this doesn't help you, please upload your game log to a service like pastebin.
