I have an on client event that is not working with one of the things im trying to do?

I have a on client event from a regular script to a local script for whenever a player or character is added which works, but when i reset and it fires it again it gives me an error even though it worked the first time. Along with this i have a script that inserts a part with a proximity prompt inside of it and thats what i want to be effected,

Just Adding the code :)

server client trigger

game.Players.PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(char)
		game.ReplicatedStorage.Event1:FireClient(player)
	end)
end)

Local script function

wait(2)
local player = game.Players.LocalPlayer.Name 
local char = game.Workspace:FindFirstChild(player)
game.ReplicatedStorage.Event1.OnClientEvent:Connect(function(plr)
	wait(2)
	print("Worked")
	wait(5)
	char.TorsoPart.ProximityPrompt.Enabled = false
	end)
