How can I make this character loading system more reliable?

Help and Feedback Code Review

Hello! I have a game that uses custom characters instead of Roblox avatars.

However, the character loading system seems a little unreliable to me.

The Code:

local ChangeChar = function(player,charModel)
	player:LoadCharacter()
	local currentChar = player.Character
	local pos = currentChar.PrimaryPart.CFrame
	
	local animate = charModel:FindFirstChild("Animate")
	local health = charModel:FindFirstChild("Health")
	
	local curAnimate = currentChar:FindFirstChild("Animate")
	local curHealth = currentChar:FindFirstChild("Health")
	
	if not health and curHealth then
		curHealth:Clone().Parent = charModel
		curHealth:Destroy()
	end 
	
	charModel.Name = player.Name
	charModel.Parent = workspace
	player.Character = charModel
	charModel.PrimaryPart:SetNetworkOwner(player)
	charModel.PrimaryPart.CFrame = pos
	
	if not animate and curAnimate then
		curAnimate:Clone().Parent = charModel
		curAnimate:Destroy()
	end
	
	if not charModel.Humanoid:FindFirstChildOfClass("Animator") then
		local animator = new("Animator")
		animator.Parent = charModel.Humanoid
	end
	
	currentChar:Destroy()
	
	for _,v in pairs(starterCharScripts:GetChildren()) do
		if not charModel:FindFirstChild(v.Name) then
			v:Clone().Parent = charModel
		end
	end
	
	ChangeCamSubject:FireClient(player,charModel.Humanoid)
	
	charModel.Humanoid.Died:Connect(function()
		wait(game.Players.RespawnTime)
		updateChar(player)
	end)
end

updateChar = function(player)
	local equippedChar = player.EquippedCharacter.Value
	local chars = player.Characters
	local curChar = player.Character or player.CharacterAdded:Wait()
	local changing = player.ChangingChar
	
	if changing.Value then
		repeat wait(0.1) until not changing.Value
	end
	
	changing.Value = true
	if chars:FindFirstChild(equippedChar) then
		local module = game.ServerStorage.Characters:FindFirstChild(equippedChar)
		if module then
			local char = module:FindFirstChildOfClass("Model")
			ChangeChar(player,char:Clone())
		else
			player:LoadCharacter()
		end
	else
		player:LoadCharacter()
	end
	
	wait(0.1)
	changing.Value = false
end

If you have suggestions, please let me know! Thanks, WE
