Why does this return an empty folder?

local DSService = game:GetService('DataStoreService'):GetDataStore('WOOPPOLICE1')
local HttpService = game:GetService('HttpService')

local defaultData = {
	PlayerStats = {
		Name = "None",
		Title = "None",
		Rank = "None",
		Race = "None",
		Birth = "None",
		Shirt = "None",
		Pants = "None",
		Class = "None",
		Lives = 5,
		Days = 0,
		Money = 0,
		Karma = 0,
		Gender = "None",
		LastRewardTick = "",
		}, 
	Skills = {
		Skill1 = {
			SkillEXP = 0,
			SkillLevel = 1,
			SkillRank = "Novice",			
		},
	},
	Equipment = {
		Armor = "None",
		MainHand = "None",
		OffHand = "None",
		Epautlet = "None",
	},
	Inventory = {

	}
}

local function buildDataEntryFromFolder(folder)
    local dataEntry = {}

    for _, valueObject in next, folder:GetChildren() do
        if valueObject:IsA("ValueBase") then
            dataEntry[valueObject.Name] = {valueType = valueObject.ClassName, value = valueObject.Value}
        end
    end

    return dataEntry
end

function unloadData(player, data)
	local newDataFolder = Instance.new("Folder", player)
	newDataFolder.Name = "PlayerData"
	local function recursive(folder, children)
		for x, y in pairs (children) do
			if typeof(y) == 'table' then
				local newFolder = Instance.new("Folder", folder)
				newFolder.Name = x
				recursive(newFolder, y)
			elseif typeof(y) == 'number' then
				local value = Instance.new("NumberValue", folder)
				value.Name = x
				value.Value = y

    local dataEntry = buildDataEntryFromFolder(player.PlayerData)
    DSService:SetAsync(player.UserId, dataEntry)
end

local function loadPlayerData(player)
    local dataEntry = DSService:GetAsync(player.UserId)

    --  In case there's no data found for the player, construct the data folder from a blank template
    if not dataEntry then
        dataEntry = defaultData
    end

	unloadData(player, dataEntry)
	
end

	loadPlayerData(player)
end)

game.Players.PlayerRemoving:Connect(function(player)
	savePlayerData(player)
end)

Fresh data reset, it makes my folder. I change a value to see if it saves or not, I rejoin, and it makes the PlayerData folder, but nothing in it. Been working with this for 6'ish hours with so many different variations and at this point i'm just lost. Any help is VERY much appreciated.

Your save data was messed up, heres your fix (look into buildDataEntryFromFolder)

local DSService = game:GetService('DataStoreService'):GetDataStore('WOOPPOLICE1')

local defaultData = {
    PlayerStats = {
        Name = "None",
        Title = "None",
        Rank = "None",
        Race = "None",
        Birth = "None",
        Shirt = "None",
        Pants = "None",
        Class = "None",
        Lives = 5,
        Days = 0,
        Money = 0,
        Karma = 0,
        Gender = "None",
        LastRewardTick = "",
        }, 
    Skills = {
        Skill1 = {
            SkillEXP = 0,
            SkillLevel = 1,
            SkillRank = "Novice",           
        },
    },
    Equipment = {
        Armor = "None",
        MainHand = "None",
        OffHand = "None",
        Epautlet = "None",
    },
    Inventory = {
        Tools = {},
        Materials = {},     
    }
}

local function buildDataEntryFromFolder(folder)
    
	local dataEntry = {}
	
	local total = 0
	recursive = function(tFolder, pFolder) --tableFolder, parentFolder
		
		for _, data in pairs(pFolder:GetChildren()) do
			
			print(data, data:IsA("ValueBase"), data:IsA("ValueBase") and data.Value or false)
			tFolder[data.Name] = data:IsA("ValueBase") and data.Value or {}
			
			if #data:GetChildren() > 0 then
				
				recursive(tFolder[data.Name], data)
				
			end
						
		end
		
	end
	
	recursive(dataEntry, folder)
	
	return dataEntry
   
end

function unloadData(Player, tFolder)
   
	Instance.new("Folder", Player).Name = "PlayerData"

   function recursive(folder, children)
        for k, v in pairs(children) do

			local child = Instance.new(typeof(v), folder)
			child.Name = k
			
			if type(v) ~= "table" then
				child.Value = v
			else
				recursive(child, v)
			end

        end
    end

    recursive(Player.PlayerData, tFolder)

end

local function savePlayerData(player)
    local dataEntry = buildDataEntryFromFolder(player.PlayerData)
    local success, err = pcall(function() DSService:SetAsync(player.UserId, dataEntry) end)
	
	if success then
		print("Saved Successfully")
	else
		print("Error: " .. err)
	end
	
end

local function loadPlayerData(player)
	
    local dataEntry = DSService:GetAsync(player.UserId)

    --  In case there's no data found for the player, construct the data folder from a blank template
