Any way to make this script actually function in studio?

It works in a published place, as proved by an acquaintance on Scripting Helpers, but I need it to function in studio.

game.Players.PlayerAdded:connect(function(plr)
	plr.CharacterAppearanceLoaded:connect(function(plrModel)
		plr:ClearCharacterAppearance()
	end)
end)

In the Ribbon go to Test, then in the Clients and Servers area, Setup the amount of Players and click Start.

Hopefully this will work,

Good luck.

Image Sample

Click "Play" on the top of the screen, or if you do not want to spawn in but still have scripts running go to the top and click "Test" then click the arrow underneath it and click "Run"
