Cannot craft

I cannot craft anything whilst in a realm. The item will appear in my inventory for half a second before vanishing again. Both the item I crafted, and the items used to craft said item are nowhere to be found. It started off just glitching out with a cake, which I have seen mentioned before; but it is now at the point where I cannot craft anything at all, making the game essentially unplayable.

I can seemingly craft fine in my own single player world's, but am completely unable to on the realm I am a part of.
