I am not sure if this is a mod conflict due to my modpack, but I have discovered that the crafting recipe for the workstation is missing and the only hint I have to it is this error:

seeing as it's referencing the crafting table, I DO have a mod called Cosmetic Wood that adds different wood variants of a crafting bench, bookshelf, and some other blocks, i'm not sure how it does this but I am asking for help to pinpoint the problem in hopes I can resolve it.
