This script makes my character die and respawn continuously, why?

Here is the code, I'm not sure if I need to add debounce to it, or what the problem is. When I use it on a custom model when I spawn in I die instantly, and then I respawn, die. Continuously. When used with a dummy model from animation editor, I spawn in the middle of the map, not my spawn point, and am stuck in the air, unable to move. Any advice would be greatly appreciated. Here is the code:

local char = game.ServerStorage.CustomCharacter -- The character to load
local respawnTime = 2.5 -- How many seconds the player remains dead before they respawn

game.Players.CharacterAutoLoads = false -- Disable default character loading

function playerAdded(player)
    if player.Character and player.Character.Parent then -- Destroy an already-existing character
        player.Character:Destroy()
    end

    while player.Parent do -- Repeat until they leave the game
        loadChar(player) -- Method waits until they die
        wait(respawnTime)
    end
end

function loadChar(player)
    local char = char:clone()
    char.Name = player.Name

    local humanoid
    for i, child in pairs(char:GetChildren()) do -- Find the humanoid
        if child.ClassName == "Humanoid" then
            humanoid = child
            break
        end
    end

    if not humanoid then -- If no humanoid was found, make one
        humanoid = Instance.new("Humanoid", char)
    end

    player.Character = char
    char.Parent = game.Workspace
    humanoid.Died:wait() -- Wait until they die
end

game.Players.PlayerAdded:connect(playerAdded)

for i, player in pairs(game.Players:GetPlayers()) do -- Play Solo support
    if player.Character then
        player.Character:Destroy()
    end

    playerAdded(player)
end
