Why doesn't my upVector or lookVector change?

When I'm using CFrame.Angles my upVector and lookVector doesnt change, if I even set them to the lowest number possible nothing changes, I tried using Orientation instead of CFrame.Angles but for some reason Orientation just doesn't work.

The thing I'm scripting is a tree that's supposed to tween out of the ground and when i'm using CFrame.Angles the tree doesn't fully come out of the baseplate. It get's stuck and if I try using Orientation the tree ends up getting flipped over even though its the same numbers on the math.rad and vector3.new

(sorry if that was hard to understand im not really good at explaining stuff)

here's the code

local rp = game:GetService("ReplicatedStorage")
local treeEvent = rp:WaitForChild("treeEvent")
local tree = rp:WaitForChild("Tree"):Clone()

treeEvent.OnServerEvent:Connect(function(player)

	local char = player.Character
	local hum = char:WaitForChild("Humanoid")
	local HRP = char:WaitForChild("HumanoidRootPart")
	
	local ts = game:GetService("TweenService")
	local treepos = {}
	
	local Dmg = script.Dmg:Clone()
	
	
	print("Event fired.") -- reminder that it works
	
	
	tree.CFrame = HRP.CFrame + (-HRP.CFrame.upVector*195)
	wait()
	tree.Parent = workspace
	
	script.Dmg.Player.Value = player.Name
	
	Dmg.Parent = tree
	Dmg.Disabled = false
	
	local treeori = HRP.CFrame * CFrame.Angles(math.rad(-90),0,0)
	
	
	
	treepos.CFrame = HRP.CFrame + (HRP.CFrame.upVector * 195)
	treepos.CFrame = HRP.CFrame + (HRP.CFrame.lookVector * 50)
	treepos.CFrame = treeori
 	
	
	local tweenInfo = TweenInfo.new(
		2.7,
		Enum.EasingStyle.Quad,
		Enum.EasingDirection.Out,
		0,
		false,
		0
	)
	
	local treeTween = ts:Create(tree, tweenInfo, treepos)
	wait()
	treeTween:Play()
	
	wait(8)
	tree:Remove()
		
end)

script with orientation instead of CFrame.Angles
