player parameter without player added function?

Code:

local x = game:GetService("TweenService")

local gv = Instance.new("BoolValue", game.ReplicatedStorage)
gv.Value = false -- open

local validRanks = {"Developer", "Phoenix Guard", "Peacekeeper", "Council Members","Phoenix Council Members",  "Cardinal Witch/Warlock","Majestic Being" }

function playerIsValidRank(player)
	local playerRank = player:GetRoleInGroup(5527515)

	for _, rank in pairs(validRanks)do
		if playerRank  == rank then
			return true
		end
	end
end

game.Players.PlayerAdded:Connect(function(player)
	print(playerRank)

	local wplayer = game.Workspace:WaitForChild(player.Name)

	player.Chatted:Connect(function(message)
		local foundMessage = string.find(message:lower(), "colloportus") 

		if  foundMessage  and playerIsValidRank(player) then
				gv.Value = false
				local gate = game.Workspace.Gate

				for i,v in pairs(gate:GetChildren()) do
				
					local m = {Position = Vector3.new(v.Position.X, v.Position.Y+29, v.Position.Z)}
					local t = x:Create(v, TweenInfo.new(3.2, Enum.EasingStyle.Sine, 	Enum.EasingDirection.InOut, 0, false, 0), m)
					t:Play()
				end
			end
		end
	end)
end)

game.Players.PlayerAdded:Connect(function(player)
	local playerrank = player:GetRoleInGroup(5527515)
	print(playerrank)
	local wplayer = game.Workspace:WaitForChild(player.Name)

	player.Chatted:Connect(function(message)
		local foundMessage = string.find(message:lower(), "alohomora") 

		if  foundMessage  and playerIsValidRank(player) then
			if gv.Value == false then 
				gv.Value = true 
				local gate = game.Workspace.Gate
				
				for i,v in pairs(gate:GetChildren()) do
				
					local m = {Position = Vector3.new(v.Position.X, v.Position.Y-29, v.Position.Z)}
					local t = x:Create(v, TweenInfo.new(3.2, Enum.EasingStyle.Sine, Enum.EasingDirection.InOut, 0, false, 0), m)
					t:Play()
				end
			end
		end
	end)
end)

Basically, if 1 person joins, it works, but if 2 people join, it breaks i need the player parameter without playeradded,playerleft
