Pathfinding NPC bugging out

[iFlameyz (Flameyz)]

Making an npc move around waypoint randomly and it works flawlessly, but sometime the npc just starts freezing for split seconds, and sometimes the npc moves perfectly

local PathfindingService = game:GetService("PathfindingService")
local PhysicsService = game:GetService("PhysicsService")

local dummy = script.Parent
local Humanoid = dummy:WaitForChild("Humanoid")

local waypointParts = game.Workspace.Waypoints:GetChildren()
local running = false

for i, v in pairs(dummy:GetDescendants()) do
	if v:IsA("Part") or v:IsA("BasePart") or v:IsA("MeshPart") then
		PhysicsService:SetPartCollisionGroup(v, "Player")
	end
end

local path = PathfindingService:CreatePath({
	AgentRadius = 3,
	AgentHeight = 6,
	AgentCanJump = false,
	WaypointSpacing = 0.5,
})

local waypoints = nil
local nextWaypointIndex = nil
local blockedConnection = nil
local reachedConnection = nil

local function followPath(destination)
	running = true
	
	local success, err = pcall(function()
		path:ComputeAsync(dummy.HumanoidRootPart.Position, destination)
	end)
	
	if success and path.Status == Enum.PathStatus.Success then
		waypoints = path:GetWaypoints()
		
		blockedConnection = path.Blocked:Connect(function(blockedWaypointIndex)
			if blockedWaypointIndex >= nextWaypointIndex then
				blockedConnection:Disconnect()
				followPath(destination)
			end
		end)
		
		if not reachedConnection then
			reachedConnection = Humanoid.MoveToFinished:Connect(function(reached)
				if reached and nextWaypointIndex < #waypoints then
					nextWaypointIndex += 1
					Humanoid:MoveTo(waypoints[nextWaypointIndex].Position)
				else
					reachedConnection:Disconnect()
					blockedConnection:Disconnect()
					running = false
					print(running)
				end
			end)
		end
		
		nextWaypointIndex = 2
		Humanoid:MoveTo(waypoints[nextWaypointIndex].Position)
	end
	
end

while wait(3) do
	if not running then
		local randomPickedPart = waypointParts[math.random(1, #waypointParts)]
		
		if randomPickedPart then
			
			waypoints = nil
			nextWaypointIndex = nil
			blockedConnection = nil
			reachedConnection = nil
			
			followPath(Vector3.new(math.random(1,5), 0, math.random(1,5)) + randomPickedPart.Position)
		end
	end
end

Btw for the collision groups Player x Player can’t collide

You neeed to remember to VehicleSeat:SetNetworkOwner(nil) for so that the server handles all NPC physics and not default to the nearest player. I think you can do this just on the primarypart but I tend to do it on all npc parts
