[Tvede-dk]

in short the error is

Failed to load mods: Error while loading recipe prototype "sand" (recipe): In RecipePrototype, `category` and `additional_categories` got merged into `categories` table. Please use that instead.

and the fix is in recipe-updates.lua at line 284

data.raw.recipe["sand"].categories = util.k2() and {"kr-crushing"} or {"basic-crushing"}
