i have also tried setting the item after the inventory is opened, same issue:

public void openStonecutterGUI(Player player) {
Inventory inventory = Bukkit.createInventory(null, InventoryType.STONECUTTER, "text");
ItemStack stone = new ItemStack(Material.STONE);
player.openInventory(inventory);
inventory.setItem(0, stone);
}

Can reproduce this on 1.20.5 with commit 8f7ac62

Might be hard coded by the client, cant get any other crafting stations to display items except for ones like furnace and brewing stand (that actually have containers on the server)
