CanCollide not working on my character?

Hello! I made a script to make me go through parts in the workspace, to do so I used a RemoteEvent that makes each part of my character CanCollide = false and it actually works, but it still won't let me go through parts. Here is my script. :) Any help?

local db = false
local Character = script.Parent.Parent.Parent


game.ReplicatedStorage.RemoteEvents.PermeationSkill.Permeate.OnServerEvent:Connect(function(plr)
    plr.Character.Humanoid.MaxHealth = 15
    plr.Character.Humanoid.Health = 15

    for i,v in pairs(Character:GetDescendants()) do
        if v:IsA("BasePart") then
            v.CanCollide = false
            v.Transparency = 0.65
            Character.Humanoid.WalkSpeed = 7
        end
    end
end)

local PS = game:GetService("PhysicsService")
PS:CreateCollisionGroup("Player")
PS:CollisionGroupSetCollidable("Player","Player",false)

game.Players.PlayerAdded:Connect(function(Player)
	Player.CharacterAdded:Connect(function(Character)
		Character:WaitForChild("HumanoidRootPart")
		Character:WaitForChild("Head")
		Character:WaitForChild("Humanoid")
		for i,v in pairs(Character:GetChildren()) do
			if v:IsA("BasePart") then
				PS:SetPartCollisionGroup(v,"Player")
			end
		end
	end)
end)

The HumanoidRootPart Is Can Go Through, But The Other Parts Cant.

You Need To Change The Cancollide For Every Part.

If You Want It To Do It By Script,

for _, child in pairs(script.Parent:GetChildren()) do
		if child:IsA("Part") then
			child.Cancollide = false
		end
		
		-- You Can Also Put An Elseif instead.
		if child:IsA("BasePart") then
			child.Cancollide = false
		end
	end

Or Manually,

Select Each Body Parts And Change The Cancollide.

I just fixed this by using a Touched event and make the parts I touch CanCollide = false.
