How to apply a character to a rig using the player's name

Hello, I’ve been trying to solve this for hours, but I couldn’t figure it out, so I’m posting here. (I’m using a google translator.)
There is an R6 rig in the workspace. I’m working on a script where the rig changes to the player’s character when the player enters their username in a GUI textbox.

local Players = game:GetService("Players")
local TextBox = script.Parent.Parent.MainFrame.AnimationScrollingFrame.PlayerNameTextBox

-- Dummy rig reference in workspace
local MainRig = workspace:WaitForChild("MainRig")

-- Create StringValue for UserId if it doesn't exist
local userIdValue = MainRig:FindFirstChild("UserId")
if not userIdValue then
	userIdValue = Instance.new("StringValue")
	userIdValue.Name = "UserId"
	userIdValue.Parent = MainRig
end

-- Function to reset the model's appearance
local function resetModel()
	for _, item in pairs(MainRig:GetChildren()) do
		if item:IsA('CharacterMesh') or item:IsA('Shirt') or 
			item:IsA('Pants') or item:IsA('Accessory') or 
			item:IsA('ShirtGraphic') then
			item:Destroy()
		end
	end

	if MainRig.Head:FindFirstChild('Mesh') then
		MainRig.Head.Mesh:Destroy()
	end
end

-- Function to update the model's appearance
local function updateModel(userId)
	local success, error = pcall(function()
		local appearance = Players:GetCharacterAppearanceAsync(userId)

		for _, item in pairs(appearance:GetChildren()) do
			if item:IsA('SpecialMesh') or item:IsA('BlockMesh') or item:IsA('CylinderMesh') then
				item.Parent = MainRig.Head
			elseif item:IsA('Decal') then
				MainRig.Head.face.Texture = item.Texture
			elseif item:IsA('BodyColors') or item:IsA('CharacterMesh') or 
				item:IsA('Shirt') or item:IsA('Pants') or item:IsA('ShirtGraphic') then
				if MainRig:FindFirstChild('Body Colors') then
					MainRig['Body Colors']:Destroy()
				end
				item.Parent = MainRig
			elseif item:IsA('Accessory') then
				item.Parent = MainRig
				item.Handle.CFrame = MainRig.Head.CFrame * CFrame.new(0, MainRig.Head.Size.Y / 2, 0) * 
					item.AttachmentPoint:inverse()
			end
		end

		if not MainRig.Head:FindFirstChild('Mesh') then
			local mesh = Instance.new('SpecialMesh', MainRig.Head)
			mesh.MeshType = Enum.MeshType.Head
			mesh.Scale = Vector3.new(1.25, 1.25, 1.25)
		end
	end)

	if not success then
		warn("Failed to update appearance:", error)
	end
end

-- Function to handle the username input
local function onUsernameSubmitted(username)
	local success, userId = pcall(function()
		return Players:GetUserIdFromNameAsync(username)
	end)

	if success and userId then
		resetModel()
		userIdValue.Value = userId
		updateModel(userId)
	else
		warn("Failed to get UserId for username:", username)
	end
end

-- Connect the TextBox's FocusLost event
TextBox.FocusLost:Connect(function(enterPressed)
	if enterPressed then
		local username = TextBox.Text
		if username ~= "" then
			onUsernameSubmitted(username)
		end
	end
end)

I wrote the code as described above, but some accessories were not loaded in the correct position and were not properly anchored. Also, the code looks a bit complicated—would there be a simpler way to achieve this?
Thank you for reading!

Humanoid:ApplyDescription() build in method to load appearance of a player onto a character, look into it it’s very useful and simpler then what you’re going
