Animations won't play for some people, but works perfectly for others?

script.Parent.Selected:connect(function(Oceanview)
	Oceanview.Button1Down:connect(function()
		 waves = game.Players.LocalPlayer.Character.Humanoid
		 current = waves:LoadAnimation(script.Parent.Animation)
		current:Play()
	end)
end)

This script is put inside a local script inside of a tool, along with a Animation. It worked a few weeks ago perfectly, all of the animations played immediately when you join without a problem, but now I've been getting complaints of the animations not playing for people and people having an issue of not being able to turn off their camera.

Theres over 100 animation tools inside the game, and the game has also been getting complaints of lag. I know for sure it isn't because of a virus because I didn't insert any free models at the time of the animation issue.

I thought it might have been an issue with a player not being able to load the animation, but one player says they waited over 20 minutes for the animation to load in, but it has yet to work.

What might be the issue that caused the animations not to load for some?

put it in a script and not a local script if it's in a GUI make a local script but use a remote event
