Portal kills me when i enter it

So i created portals and i input a script in them. But for some reason it kills me when i step in it, this is the script for both parts.

local player = hit.Parent
if player then
local torso = player.HumanoidRootPart
if torso then
torso.Position = Vector3.new(44.5, 111, 30)

Updating the Position property disregards any and all welds (or more specifically Motor6D joints) a character has, thus killing them.

To teleport a character, you need to update its CFrame.

torso.CFrame = CFrame.new(44.5, 111, 30)

If you want to preserve the orientation of character body (same as they entered the portal) use:

torso.CFrame = torso.CFrame - torso.Position + Vector3.new(44.5, 111, 30)

You should always use CFrame when moving the HumanoidRootPart. Setting the vector3 only moves the HumanoidRootPart and not the rest of the character.

Just Move the Character Model using Model:MoveTo()

local hum = hit.Parent:FindFirstChild("Humanoid") -- to ensure the item is a character model by getting the Humanoid

if hum then -- if the Humanoid Exists
    hum.Parent:MoveTo(Vector3.new(44.5, 111, 30)) -- moves Model which is their character
