I created two team switch buttons in the form of GUI. It's made so that the GUI is supposed to disappear upon being clicked but it doesn't. It worked, before I added a death upon clicking the button so the player is respawned at the corresponding team spawn. I don't know if the death is the problem, or if it's just some other part of the script.

Two scripts responsible for the team switch:

local rstorage = game:GetService("ReplicatedStorage")
local brightblue = rstorage.Brightblue
local brightred = rstorage.Brightred

local playeradded = rstorage.PlayerAdded

local bluebutton = script.Parent:WaitForChild("Raider")
local redbutton = script.Parent:WaitForChild("Ally")

local gui = script.Parent

playeradded.OnClientEvent:connect(function()
	gui.Enabled = true
	
	bluebutton.MouseButton1Click:connect(function()
		local splayer = game:GetService("Players")[game:GetService("Players").LocalPlayer.Name]
		brightblue:FireServer(splayer)
	end)
	
	redbutton.MouseButton1Click:connect(function()
		local splayer = game:GetService("Players")[game:GetService("Players").LocalPlayer.Name]
		brightred:FireServer(splayer)
	end)
end)

local rstorage = game:GetService("ReplicatedStorage")
local brightblue = rstorage.Brightblue
local brightred = rstorage.Brightred

local playeradded = rstorage.PlayerAdded


game.Players.PlayerAdded:connect(function(player)
	wait()
	playeradded:FireClient(player)
end)

brightblue.OnServerEvent:connect(function(splayer)
	splayer.TeamColor = BrickColor.new("Bright blue")
	splayer.Character.Humanoid.Health = 0
	splayer.leaderstats.Wipeouts.Value = splayer.leaderstats.Wipeouts.Value - 1
end)

brightred.OnServerEvent:connect(function(splayer)
	splayer.TeamColor = BrickColor.new("Bright red")
	splayer.Character.Humanoid.Health = 0
	splayer.leaderstats.Wipeouts.Value = splayer.leaderstats.Wipeouts.Value - 1
end)
