Part is nil but physically exists

[EnvisionDev (envision)]

I am not entirely sure if this it a bug or not but I am experiencing a really weird problem.

I am trying to setup this camera module that is working perfectly fine on another baseplate but when I add it to a separate baseplate it is giving me the following.

--[[

	:Enable() -- Enables the menu camera

	:Disable() -- Disables the menu camera

--]]

print(workspace:FindFirstChild('Selection'))
print(workspace:FindFirstChild('Selection'):FindFirstChild('Interactables'))
print(workspace:FindFirstChild('Selection'):FindFirstChild('Interactables'):FindFirstChild('selectorCamera'))

local MenuCamera = {
	Camera = workspace.CurrentCamera;
	CF0 = workspace:FindFirstChild('Selection'):FindFirstChild('Interactables'):FindFirstChild('selectorCamera').CFrame; -- origin CFrame based on an invisible Part instance which is used to easily position the camera in Studio

	-- These max values determine how much the camera will rotate based on the mouse's position
	MaxXRotation = 10; -- Degrees, accounts for both negative and positive directions.
	MaxYRotation = 10; -- Degrees, accounts for both negative and positive directions
}

local Player = game.Players.LocalPlayer
local Mouse = Player:GetMouse()

function MenuCamera.Enable(self)
	if self.Connection then
		self.Connection:Disconnect() -- Disconnect from the Mouse.Move event, if exists
	end

	self.Camera.CameraType = Enum.CameraType.Scriptable -- Set the CameraType to scriptable

	local function MouseMove()
		local XFloat = -0.5 + Mouse.X / self.Camera.ViewportSize.X
		local YFloat = -0.5 + Mouse.Y / self.Camera.ViewportSize.Y

		local CF = self.CF0 * CFrame.fromOrientation(
			math.rad(self.MaxYRotation * -YFloat)
			, math.rad(self.MaxXRotation * -XFloat)
			, 0
		)

		self.Camera.CFrame = CF
		
	end

	self.Connection = Mouse.Move:Connect(MouseMove)

	MouseMove()
end

function MenuCamera.Disable(self)
	if self.Connection then
		self.Connection:Disconnect() -- Disconnect from the Mouse.Move event, if exists
	end

	self.Camera.CameraType = Enum.CameraType.Custom -- Set the CameraType back to default
end

return MenuCamera

--// SERVICES


--// ITEMS
--# OBJECTS
local cameraModule = require(script:FindFirstChild('Camera'))

--// SCRIPTS
--# INIT
local function init()
	
	cameraModule:Enable()
	
end

wait(1)

init()

WHILE GAME IS SIMULATING:

Really hope someone can help me, or tell me if this is a roblox bug.

:FindFirstChild('selectorCamera')

It could be happening because the part hasn’t loaded in yet. Try replacing the :FindFirstChild with :WaitForChild.
