How do I fix this intermission system issue? Where did I go wrong?

I have made an intermission system, and it works when it's only one player, however, when there are two+ players, it gets stuck on intermission after the first round.

Server:

    local DSS = game:GetService("DataStoreService")
    local TotalWinsStore = DSS:GetDataStore("BETAWins")
    local TotalKillsStore = DSS:GetDataStore("BETAKills")
    local TimeLeft = 20
    local ReplicatedStorage = game:GetService("ReplicatedStorage")
    local GUIChanger = ReplicatedStorage:WaitForChild("GUIChanger")
    local GUIChangerTwo = ReplicatedStorage:WaitForChild("GUIChangerB")
    local GUIChangerThree = ReplicatedStorage:WaitForChild("GUIChangerC")

    wait(1)

    game.Players.PlayerAdded:Connect(function(p)
        local leaderstats = Instance.new("Folder", p)
        leaderstats.Name = "leaderstats"
        local TotalWins = Instance.new("IntValue", leaderstats)
        TotalWins.Name = "Wins"
        TotalWins.Value = 0
        local TotalKills = Instance.new("IntValue", leaderstats)
        TotalKills.Name = "Total Kills"
        TotalKills.Value = 0
        local RoundKills = Instance.new("IntValue", leaderstats)
        RoundKills.Name = "Round Kills"
        RoundKills.Value = 0
        local Playing = Instance.new("BoolValue", p)
        Playing.Name = "Playing"
        Playing.Value = false

        local data
        local dataII
        local success, errormessage = pcall(function()
            data = TotalWinsStore:GetAsync(p.UserId.."-wins")
            dataII = TotalKillsStore:GetAsync(p.UserId.."-kills")
        end)

        if success then
            p.leaderstats["Wins"].Value = data
            p.leaderstats["Total Kills"].Value = dataII
            print("Data saved!")
        else
            warn(errormessage)
            print("Error while loading data!")
        end
    end)

    game.Players.PlayerRemoving:Connect(function(p)
        local success, errormessage = pcall(function()
            TotalWinsStore:SetAsync(p.UserId.."-wins", p.leaderstats["Wins"].Value)
            TotalKillsStore:SetAsync(p.UserId.."-kills", p.leaderstats["Total Kills"].Value)
        end)

        if success then
            print("Success!")
        else
            warn(errormessage)
            print("Error while saving data!")
        end
    end)

    while true do
        repeat
            wait(1)
            TimeLeft = TimeLeft - 1
            GUIChanger:FireAllClients(TimeLeft)
        until TimeLeft == 0

        wait(2)

        for i,v in pairs(game.Players:GetPlayers()) do

            v.Playing.Value = true

            v.Character.HumanoidRootPart.Position = picked.Position
            wait(0.1)
        end

        GUIChangerTwo:FireAllClients()

        local alldead = false
        while alldead == false do

        function higherScoreThan(playerA, playerB)
            return playerA.leaderstats.Score.Value > playerB.leaderstats.Score.Value

                table.insert(players, player)
            end
        end

        table.sort(players, higherScoreThan)

        if players[1] then
            local Winner = players[1].Name
            GUIChangerThree:FireAllClients(Winner)
            players[1].leaderstats["Wins"].Value = players[1].leaderstats["Wins"].Value + 1
        end

        for i,v in pairs(game.Players:GetPlayers()) do
            v.leaderstats["Total Kills"].Value = v.leaderstats["Total Kills"].Value + v.leaderstats["Round Kills"].Value
            wait(0.5)
            v.leaderstats["Round Kills"].Value = 0
        end

        wait(6)

        TimeLeft = 20
    end

Client:

     local ReplicatedStorage = game:GetService("ReplicatedStorage")
    local GUIChanger = ReplicatedStorage:WaitForChild("GUIChanger")

No errors.
