NPC won't move for some reason

Hello, i don’t really know what’s happening cause i’m a noob at pathfinding, i don’t know why it doesn’t work in game. I am also using a pathfinding Module Called SimplePath

Studio:

In-Game:

This worked before, now it just doesn’t work,
The Script:

local Root = script.Parent:WaitForChild("HumanoidRootPart")
local SimplePath = require(game.ReplicatedStorage.SimplePath)



local function findTarget()
	local players = game.Players:GetPlayers()
	local MaxDis = 80
	local nearestTar
	
	for index, player in pairs(players) do
		if player.Character then
			local Target = player.Character
			local Distance = (script.Parent.HumanoidRootPart.Position - Target.HumanoidRootPart.Position).Magnitude
			if Distance < MaxDis then
				nearestTar = Target
				MaxDis = Distance
				
			end
		end
	end
	return nearestTar
end

local function Attack(target)
	local Distance = (script.Parent.HumanoidRootPart.Position - target.HumanoidRootPart.Position).Magnitude
	if Distance > 8 then
		--script.Parent.Humanoid:MoveTo(target.HumanoidRootPart.Position)
		local Path = SimplePath.new(script.Parent)
		Path:Run(target.HumanoidRootPart.Position)
	else
		target.Humanoid.Health = 0
	end
end

function wander()
	local xRan = math.random(-80,80)
	local zRan = math.random(-80,80)

	local goal = Root.Position + Vector3.new(xRan,0,zRan)
	local Path = game:GetService("PathfindingService"):CreatePath()
	Path:ComputeAsync(Root.Position, goal)	
	if Path.Status == Enum.PathStatus.Success then
		print("Success")
		local WayPoints = Path:GetWaypoints()
		for i,v in ipairs(WayPoints) do
			if v.Action == Enum.PathWaypointAction.Jump then
				Root.Parent.Humanoid.Jump = true
			end
			local Target = findTarget()
			
			if Target then
				Attack(Target)
				break
			else
				local Path = SimplePath.new(script.Parent)
				Path:Run(v.Position)
				--Root.Parent.Humanoid:MoveTo(v.Position)
			--	Root.Parent.Humanoid.MoveToFinished:Wait()
			end
		end
	else
		print("Failed")
	end
end


while wait() do
	local Target = findTarget()
	if Target then
		Attack(Target)
	else
		wander()
	end
end

UPDATE:
I PUT FREE MODELS NPC AND THEY STILL DON"T MOVE IS THIS A BUG OR SOMETHING

Pathfinding is tricky, especially with complex maps. Even though your map isn’t all complex, the navigation maps can be generated not as expected. You can possibly try turning off collisions for the trees. If you wanted the trees to have collisions with players, you can turn them back on locally using a local script.
