(Answered) Why am I recieving "tables cannot be cyclic?"

I am receiving a "tables cannot be cyclic" error from line #10 of the following script:

local ServerScriptService = game:GetService("ServerScriptService")
local ChatServiceRunner = ServerScriptService:WaitForChild("ChatServiceRunner")
local ChatService = require(ChatServiceRunner.ChatService)

local giveTag = game.ReplicatedStorage.GiveTag

giveTag.OnServerEvent:Connect(function(player)
    local speaker = ChatService:GetSpeaker(player.Name)

    local class = game.ReplicatedStorage:WaitForChild(speaker):WaitForChild("Class")

    local DefaultTags = {
        {TagText = class, TagColor = Color3.new(1,0,0)},
    }
    if speaker and speaker:GetPlayer() then
        speaker:SetExtraData("Tags", DefaultTags)
    end
end)

The "class value" that line #10 is looking for is a StringValue that is generated by the script below; players' "class value" exists within its own individual folder sharing the same name as its designated player.

game.Players.PlayerAdded:connect(function(player)
    local folder = Instance.new("Folder")
    folder.Parent = game.ReplicatedStorage
    folder.Name = player.Name
    local Class = Instance.new("StringValue", folder)
    Class.Name = "Class"
    Class.Value = "No class"
end)

If additional clarification is needed, please don't hesitate to tell me. All help is appreciated!
