Changing Humanoid's name leads to corescript errors

Bug Reports Studio Bugs
#1

If you rename Humanoid in a Character, a core script related to Self View (selfie view) will error from time to time:

Error message/details 
  16:53:29.653  CoreGui.RobloxGui.Modules.SelfieView.Utils.ModelUtils:92: attempt to index nil with 'IsA'  -  Client

Repro

  1. Use this serversided script (or rename it through the Explorer):
Code 
local Players = game:GetService("Players")

local function PlayerAdded(player: Player): ()
    local function CharacterAdded(character: Model): ()
        local humanoid = character:FindFirstChildOfClass("Humanoid")
        humanoid.Name = "Core"
    end    
    
    player.CharacterAdded:Connect(CharacterAdded)
    local character = player.Character
    if (character) then
        task.spawn(CharacterAdded, character)
    end
end

Players.PlayerAdded:Connect(PlayerAdded)
for _, player: Player in Players:GetPlayers() do
    task.spawn(PlayerAdded, player)
end
  1. Spawn in-game and wait a bit.
  2. Errors will start to appear in the console output from a core-script in CoreGui.

We’ll look into this. There may be some reliance on the Humanoid being named Humanoid in some areas of the code, so it’s not a good idea to rename it, but we will look into making it not error in this case
