Minigame script gone wrong, what should I do?

So I created a script for some minigames from a tutorial I watched. I decided to be original, so I also added a ScreenGui for the announcements. Originally, the script looked like this,

minigames = game.Lighting.Minigames:GetChildren()
h = Instance.new("Hint")
while true do
	if game.Players.NumPlayers > 1 then
		h.Text = "Deciding What Game To Play..."
		wait(3)
		rangame = math.random(1, #minigames)
		gamechosen = minigames [rangame]
		h.Text = "Game Chosen!"
		wait(2)
		h.Text = "We Are Playing:" ..gamechosen.Name
		wait(3)
		gamechosenclone = gamechosen:Clone()
		gamechosenclone.Parent = Workspace
		wait(3)
		spawns = gamechosenclone.Spawns:GetChildren()
		for i,v in pairs(game.Players:GetPlayers()) do
			name = v.Name
			check = Workspace:FindFirstChild(name)
			if check then
				checkhumanoid = check:FindFirstChild("Humanoid")
				if checkhumanoid then
					check:Moveto(spawns[i])
				end
			end
		end
		for i = 3, 1, -1 do
			h.Text = "Game Begins In:" ..i
			wait(1)
		end
		for i = 10, 1, -1 do
		h.Text = "Time Left:" ..i
		end
		h.Text = "The Game Has Finished!"
		gamechosenclone:Destroy()
	else
		h.Text = "One Player Is Not Enough!"
	end
	wait(1)
end

This script worked perfectly for me, and I was very happy, but then I added my own twist

minigames = game.Lighting.Minigames:GetChildren()
GuiStatus = game.StarterGui.StatusBar.Main.Status
while true do
	if game.Players.NumPlayers > 1 then
		GuiStatus.Text = "Deciding What Game To Play..."
		wait(3)
		rangame = math.random(1, #minigames)
		gamechosen = minigames [rangame]
		GuiStatus.Text = "Game Chosen!"
		wait(2)
		GuiStatus.Text = "We Are Playing:" ..gamechosen.Name
		wait(3)
		gamechosenclone = gamechosen:Clone()
		gamechosenclone.Parent = Workspace
		wait(3)
		spawns = gamechosenclone.spawns:GetChildren()
		for i,v in pairs(game.Players:GetPlayers()) do
			name = v.Name
			check = Workspace:FindFirstChild(name)
			if check then
				checkhumanoid = check:FindFirstChild("Humanoid")
				if checkhumanoid then
					check:MoveTo(spawns[i])
				end
			end
		end
		for i = 3, 1, -1 do
			GuiStatus.Text = "Game Begins In:" ..i
			wait(1)
		end
		for i = 10, 1, -1 do
		GuiStatus.Text = "Time Left:" ..i
		end
		GuiStatus.Text = "The Game Has Finished!"
		gamechosenclone:Destroy()
	else
		GuiStatus.Text = "One Player Is Not Enough!"
	end
	wait(1)
end

this was the new script, I created a textlabel, parented by a frame, parented by a screengui, under startergui. The script only displays "One Player Is Not Enough" on the screenGUI even if there are multiple players. The actual minigame script only runs up to the cloning of the minigame, then immediately stops and stays. It says "Unable to cast instance to Vector3". What should I fix? What have I done wrong?

You're only updating the gui in the StarterGui, not the guis for the players. The players will only see the changes when they respawn. Try this:

local minigames = game.Lighting.Minigames:GetChildren()
local GuiStatus = game.StarterGui.StatusBar.Main.Status

function updateGui(text)
	GuiStatus.Text = text
	for i,v in ipairs(game.Players:GetPlayers()) do
		pcall(function()
			v.PlayerGui.StatusBar.Main.Status.Text = text
		end)
	end
end
	
while true do
	if game.Players.NumPlayers > 1 then
		updateGui("Deciding What Game To Play...")
		wait(3)
		rangame = math.random(1, #minigames)
		gamechosen = minigames[rangame]
		updateGui("Game Chosen!")
		wait(2)
		updateGui(("We Are Playing:" ..gamechosen.Name))
		wait(3)
		gamechosenclone = gamechosen:Clone()
		gamechosenclone.Parent = Workspace
		wait(3)
		local spawns = gamechosenclone.spawns:GetChildren()
		for i,v in pairs(game.Players:GetPlayers()) do
			local name = v.Name
			local check = Workspace:FindFirstChild(name)
			if check then
				local checkhumanoid = check:FindFirstChild("Humanoid")
				if checkhumanoid then
					check:MoveTo(spawns[i])
				end
			end
		end
		for i = 3, 1, -1 do
			updateGui(("Game Begins In:" ..i))
			wait(1)
		end
		for i = 10, 1, -1 do
		updateGui((Time Left:" ..i))
		end
		updateGui("The Game Has Finished!")
		gamechosenclone:Destroy()
	else
		updateGui("One Player Is Not Enough!")
	end
	wait(1)
end

As for your other problem, check to make sure there isn't something called the name already in the Workspace that isn't a model
