Unknown Error 4450 & 4480

I've been trying to burn CDs in iTunes. One worked, however every other one after that, it doesn't even burn one song to the CD before it cancels the burn and says "An unknown error occurred. (4450)" or An unknown error occurred. (4850)" I've done a Google search and tried several suggestions (lowering the burn speed - I lowered it down to 12x and left iTunes to burn undisturbed), but to no avail. Any other suggestions? I had this problem on my old laptop but I assumed it was the CD drive because the computer was fairly old, but I only bought this laptop brand new in January. Starting to think I'll abandon using iTunes for burning CDs altogether if nothing can stop these errors occurring. As far as I'm aware I have the latest iTunes and I'm running Windows 10.
