Screen staying black when opening menu in Pokégear

[Seedonator]

Okay so I've made an option in the Pokégear to go to the global trade station. When i select the button it changes the BGM and all the functions work however you can't see the actual screen. The whole screen is black and you're basically blinded until you exit from the GTS where then you can see the Pokégear options again.
Here's my code for the Pokégear:

elsif cmdGts>=0 && cmd==cmdGts
        pbPlayDecisionSE
        pbFadeOutIn(99999){
          pbBGMPlay("Trade Resort - Brick Bronze OST")
          scene = Scene_GTS.new
          scene.main
        }

And this is the code for the GTS:

class GTSSearchMethod
  def initialize
    @exit = false
    @index = 0
  end

  def create_spriteset
    pbDisposeSpriteHash(@sprites) if @sprites
    @sprites = {}
    @sprites["background"] = IconSprite.new
    @sprites["background"].setBitmap("Graphics/Pictures/GTS/Background")

    pbSetSystemFont(@sprites["background"].bitmap)
    textpos=[
      ["Select Search Method",50,6,0,Color.new(248,248,248),Color.new(40,40,40)],
      ["          Online ID: #{$PokemonGlobal.onlineID}",350,6,2,Color.new(248,248,248),
      Color.new(40,40,40)],
    ]
    pbDrawTextPositions(@sprites["background"].bitmap,textpos)

    @sprites["0"] = GTS_Button.new(Graphics.width/2, 50, "By Wanted")
    @sprites["0"].x -= @sprites["0"].bitmap.width / 2

    @sprites["1"] = GTS_Button.new(Graphics.width/2, 110, "By Pokémon")
    @sprites["1"].x -= @sprites["1"].bitmap.width / 2

    @sprites["2"] = GTS_Button.new(Graphics.width/2, 170, "By ID")
    @sprites["2"].x -= @sprites["2"].bitmap.width / 2

    @sprites["3"] = GTS_Button.new(Graphics.width/2, 230, "Exit")
    @sprites["3"].x -= @sprites["3"].bitmap.width / 2

    bit = Bitmap.new("Graphics/Pictures/GTS/Select")
    @sprites["selection_l"] = IconSprite.new
    @sprites["selection_l"].bitmap = Bitmap.new(16, 46)
    @sprites["selection_l"].bitmap.blt(0, 0, bit, Rect.new(0, 0, 16, 16))
    @sprites["selection_l"].bitmap.blt(0, 23, bit, Rect.new(0, 16, 16, 32))

    @sprites["selection_r"] = IconSprite.new
    @sprites["selection_r"].bitmap = Bitmap.new(16, 46)
    @sprites["selection_r"].bitmap.blt(0, 0, bit, Rect.new(16, 0, 32, 16))
    @sprites["selection_r"].bitmap.blt(0, 23, bit, Rect.new(16, 16, 32, 32))

    @sprites["selection_l"].x = @sprites["#{@index}"].x-2
    @sprites["selection_l"].y = @sprites["#{@index}"].y-2
    @sprites["selection_r"].x = @sprites["#{@index}"].x+
    @sprites["#{@index}"].bitmap.width-18
    @sprites["selection_r"].y = @sprites["#{@index}"].y-2

    pbFadeInAndShow(@sprites) { update }
  end
  
  def main
    create_spriteset
    Graphics.transition
    loop do
      Graphics.update
      Input.update
      update
      break if @exit
    end
    Graphics.freeze
    pbDisposeSpriteHash(@sprites)
  end
