tModLoader Issue with a Mod (Error graphics)

[PewPewTrash]

So, I'm making a bow (I did), but when I try to enable (not build) the mod, this error pops up

The texture file at Items/TheDevourer.png failed to load
at Terraria.ModLoader.Mod.Autoload()
at Terraria.ModLoader.ModLoader.do_Load(Object threadContext)

Inner Exception:
An unexpected error has occurred.
