Blink script not printing any errors whilist not changing the face?

Code:

game.Players.PlayerAdded:Connect(function(p)
	
    print("bruh")
	
	local head = p:FindFirstChild("Head")
	
	local face = Instance.new("Decal", head)
	
	face.Texture = "7071149315"
	
	wait(3)
	
	face.Texture = "7071149800"
	
    print("work again")
	
end)

Why doesnt it work?

Because the textures are of the "Content" type, you have to type face.Texture = "rbxassetid://7071149315" instead of what you wrote. This ensures that the ID is from Roblox's servers, and not anywhere else.

TL:DR; just copy the code below because i know ur lazy

game.Players.PlayerAdded:Connect(function(p)
    print("bruh")
    local head = p:FindFirstChild("Head")
    local face = Instance.new("Decal", head)
    face.Texture = "rbxassetid://7071149315"
    wait(3)
    face.Texture = "rbxassetid://7071149800"
    print("work again")
end)

also i think u got the ids wrong way around, it starts out with eyes open, waits 3 seconds, then permanently shuts them
