My battle system broke and i have no idea what's wrong. How do i fix it?

So uhm, it's been months since i last posted here. Hi, hello, i am not dead.

Months ago my very terrible battle system used to work, but when i tried to work on it some more today, well uh, lets say it broke.

I literally did nothing, i just went to test it before continuing anything and it flat out broke.

!!!WARNING!!!

If you have years of experience in scripting the next image may be disturbing

If you wish to continue, then wow you are a brave one

This is the script:

--Variables

local parts = game.Workspace.Parts:GetChildren()
local Players = game:GetService("Players")
local Dummy = game.Workspace.Dummy
local DummyHumanoid = Dummy.Humanoid
local debounce = false
local player = Players.LocalPlayer
local Character = player.Character
local Humanoid = Character:WaitForChild("Humanoid")
local FadeInFrame = script.Parent.Parent.FadeInUI.FadeInFrame
local attacks = require(script.Attacks)

--Battle Loop

for i, v in pairs(parts) do
    v.Touched:Connect(function(hit)
        if hit.Parent:FindFirstChild("Humanoid") then

            script.Parent.Parent.FadeInUI.Enabled = true

            Humanoid.WalkSpeed = 0
            Humanoid.JumpPower = 0

            v:Destroy()

            FadeInFrame.BackgroundTransparency = 1

            for k = 1,100 do
                FadeInFrame.BackgroundTransparency -= 0.1
                wait(0.3)
                if FadeInFrame.BackgroundTransparency == 0 then
                    break
                end
            end
            script.Parent.Parent.FadeInUI.Enabled = false

            script.Parent.Enabled = true
            Character:FindFirstChild("HumanoidRootPart").CFrame = game.Workspace.TpPart.CFrame + Vector3.new(0,1,0)

            if script.Parent.Enabled == true then
                if script.Parent.AtkSelector.Punch.MouseButton1Click then
                    script.Parent.AtkSelector.Punch.MouseButton1Click:Connect(function()
                        if not debounce then
                            debounce = true
                            DummyHumanoid.Health = DummyHumanoid.Health - 50

                            local function typeText(text)
                                for i = 1, #text do
                                    script.Parent.DialogueLabel.Text = string.sub(text, 1, i)
                                    wait()
                                end
                                wait(1.5)

                            end


                            if DummyHumanoid.Health <= 0 then
                                typeText("You won!")
                                Humanoid.WalkSpeed = 16
                                Humanoid.JumpPower = 40
                                script.Parent.AtkSelector.Punch.Visible = false
                                script.Parent.AtkSelector.Cancel.Visible = false
                                script.Parent.Enabled = false
                                DummyHumanoid.Health = 100
                                wait(3)
                                debounce = false                                                            
                            else
                                script.Parent.AtkSelector.Visible = false
                                script.Parent.AtkSelector.Punch.Visible = false
                                script.Parent.AtkSelector.Cancel.Visible = false
                                script.Parent.MagicSelector.Visible = false
                                wait(1)                 

                                typeText("This is the core battle system")
                                typeText("Isn't this cool???")                  
                                typeText("No??")
                                typeText("Welp, I tried")
                                attacks.AttackOne()

                                Humanoid.Died:Connect(function()
                                    typeText("Ded")
                                    Humanoid.WalkSpeed = 16
                                    Humanoid.JumpPower = 40
                                    script.Parent.AtkSelector.Punch.Visible = false
                                    script.Parent.AtkSelector.Cancel.Visible = false
                                    script.Parent.Enabled = false
                                    DummyHumanoid.Health = 100
                                    debounce = false
                                end)

                                wait(1)
                                script.Parent.AtkSelector.Visible = true
                                script.Parent.MagicSelector.Visible = true
                                wait(3)
                                debounce = false
                            end
                        end 
                    end)            
                end     
            end 
        end
    end)
end

Now, i know it's terrible but cope with me here.

Basically the part where it flat out stops working is:

            FadeInFrame.BackgroundTransparency = 1

            for k = 1,100 do
                FadeInFrame.BackgroundTransparency -= 0.1
                wait(0.3)
                if FadeInFrame.BackgroundTransparency == 0 then
                    break
                end
            end
            script.Parent.Parent.FadeInUI.Enabled = false

The FadeInFrame actually starts appearing, the screen becomes white and it all seems to work. But then, it just stays there.

The screen remains white, you can't move and you never get teleported to where you need to be.

For the love of god please help
