I am hoping a update comes out soon.

Since I don't have the time for testing, this build is entirely without guarantee, please feel free to try this build.

It works on 1.21.4,,, only error I was able to get is when opening an offline players backpack who had a bunch of random items

[20:16:23 ERROR]: Tried to load invalid item: 'Value 0 outside of range [1:32767] missed input: {"minecraft:unbreaking":0} missed input: {"minecraft:enchantments":{levels:{"minecraft:unbreaking":0},show_in_tooltip:0b}}'

Everything works properly though
