Why does my model delete itself and respawn me after a few seconds?

Hi so I am a beginner scripter and I'm attempting to make a titan shifting script from 'Attack On Titan. I made the basics of it and it works all the way into shifting into the actual model that I can move with. After a few seconds though the model disappears and I get respawned.

The following is the code used to transform into the model:

local NewCharacter = game.Workspace.AT --(Model, stored in Workspace to troubleshoot this)
		NewCharacter:Clone()
		NewCharacter.Parent = workspace
		game.Workspace:WaitForChild("AT")
		wait()
		Player.Character = game.Workspace.AT

Like I said, after a few seconds it just respawns me and deletes the entire model from the Workspace. Any help with this would be appreciated as I have been struggling on this for hours and my knowledge of scripting is not yet good enough to fix this error myself.

Please use the code as LocalScript.

First, at line 4, no need to use :WaitForChild since it's already loaded.

At line 6, instead of Player.Character, use game:GetService("Players").LocalPlayer.Character

I hope this helps, thank you!

That's a simple mistake even I sometimes make to this day, you forgot to set the clone to a variable. And you also assigned the character to the original model, and not the clone.

local NewCharacter = game.Workspace.AT:Clone()
NewCharacter.Parent = workspace
wait()
game.Players.LocalPlayer.Character = NewCharacter
