Just read about “new desert planet Pasaana.”
It’s a minor thing, but if you want a desert planet why not pick Jakku or Tatooine, and if you want a new planet then why another desert planet?
It would actually be very common. Any planet on the inside of the Goldilocks zone would tend to be hot and probably arid, or it could just have weird weather patterns that render much of it hot and arid.
