bad argument #2 (number expected, got Object) error when trying to remove player from table?

I'm trying to make a teleporter that teleports the player to a different place when they're in the teleporter. But if the player leaves the teleporter and the time runs out, I get this error when trying to remove the player from the table "PlayersToTP" bad argument #2 (number expected, got Object) on line 47. This is my code that I have:

local PlayerAmount = 10 -- How many players have to be in a teleporter for it to teleport
local TeleportService = game:GetService("TeleportService")
local reserveServerCode = TeleportService:ReserveServer(4820164617)
local PlayerNum = script.Parent.PlayersInTeleporter -- How many players are in the teleporter
local GuiVisible = game.ReplicatedStorage:WaitForChild("GuiVisible")
local Button = game.StarterGui.ScreenGui.TextButton
local debounce = false
script.Parent.Table.Value = false

PlayersToTP = {}


script.Parent.SurfaceGui.TextLabel.Text = "Players: 0/10"

PlayerNum.Changed:Connect(function()
	script.Parent.SurfaceGui.TextLabel.Text = "Players: "..PlayerNum.Value.."/10"
end)


script.Parent.Touched:Connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") and debounce == false then
		debounce = true
		local Humanoid = hit.Parent.HumanoidRootPart
		local char = hit.Parent
		local player = game.Players:GetPlayerFromCharacter(char)
		GuiVisible:FireClient(player)
		Humanoid.CFrame = CFrame.new(game.Workspace.TeleportPart.Position + Vector3.new(0,3,0))
		PlayerNum.Value = PlayerNum.Value +1
		table.insert(PlayersToTP,player)
		
		for i = 30,0,-1 do
			wait(1)
			script.Parent.SurfaceGui.Timer.Text = "Time Left: "..i
			if i == 0 then
				for _, v in pairs(PlayersToTP) do
					if PlayersToTP ~= nil then
						TeleportService:TeleportToPrivateServer(4820164617, reserveServerCode, PlayersToTP)
					elseif PlayersToTP == nil then
							print("No one is in the teleporter")
							script.Parent.SurfaceGui.Timer.Text = "Time Left: 30"
					end
				end
			end
		end
		
		if script.Parent.Table.Value == true then
			table.remove(PlayersToTP, player)
		end

If somebody could help me that would be great! Thanks!
