AssassinUI refusing to load the next character?

Hello; I'm trying to work on an AssassinUI and I've run into a complication with the character not loading properly and it only working once with the first character that it loads. Was trying to find out a solution before resorting to here but I've got nothing. Any help or aid to help fix this is appreciated! =)

p.s. There is no real line error it just doesnt load the actual target character somewhere near line 48 and above.

local SP = script.Parent
local Player = game.Players.LocalPlayer
wait(0.5)
local CurrentCamera = workspace.CurrentCamera
local Marketplace = game:GetService("MarketplaceService")
local GamepassId = 6800421
local HUD = SP.HUDPlayer

local SuccessfullEvent = game.ReplicatedStorage.RemoteEvents.SuccessfullKill
local Target

local function GetTarget()
    repeat wait(1)
        local randomPlayer = game.Players:GetPlayers()[math.random(1,#game.Players:GetPlayers())]
        Target = randomPlayer
    until randomPlayer.Name ~= Player.Name and randomPlayer.Team.Name ~= Player.Team.Name
end

local function Initiate()
    if --[[Marketplace:UserOwnsGamePassAsync(Player.UserId, GamepassId) and]] Player.TeamColor == BrickColor.new("Bright red") then
        script.Parent.HUDPlayer.Visible = true
        GetTarget()
        print(Target)
        if Target ~= nil and Target.Character ~= nil then
            local content, bool = game.Players:GetUserThumbnailAsync(Target.UserId, Enum.ThumbnailType.HeadShot, Enum.ThumbnailSize.Size150x150)
            HUD.TargetName.Text = Target.Name
            HUD.TargetTeam.Text = Target.Team.Name
            HUD.TargetPicture.Image = content

                print(Health)
                if Health <= 0 then
                    wait(3)
