AI seeing the player but not moving to the player

[MightBeMarbley (marbley)]

Hello! so i have a problem with the AI i’m using. So basically my map has doors and when im on the other side of a door the AI sees me but doesn’t move to me. i tried avoiding this by making collision groups so when the AI does walk to me it doesn’t get stuck (Also i got the AI from a tutorial that didn’t quite explain how it works so i have no idea how to modify this.)

Script:

local myHuman = script.Parent:WaitForChild("Humanoid")
local myRoot = script.Parent:WaitForChild("HumanoidRootPart")
local head = script.Parent:WaitForChild("Head")
local lowerTorso = script.Parent:WaitForChild("Torso")

local clone = script.Parent:Clone()

function findPath(target)
	local path = game:GetService("PathfindingService"):CreatePath()
	path:ComputeAsync(myRoot.Position,target.Position)
	local waypoints = path:GetWaypoints()

	if path.Status == Enum.PathStatus.Success then
		for _, waypoint in ipairs(waypoints) do
			if waypoint.Action == Enum.PathWaypointAction.Jump then
				myHuman.Jump = true
			end
			myHuman:MoveTo(waypoint.Position)
			local timeOut = myHuman.MoveToFinished:Wait(1)
			if not timeOut then
				myHuman.Jump = true
				print("Path too long!")
				findPath(target)
				break
			end
			if checkSight(target) then
				repeat
					print("Moving directly to the target")
					myHuman:MoveTo(target.Position)
					attack(target)
					wait(0.1)
					if target == nil then
						break
					elseif target.Parent == nil then
						break
					end
				until checkSight(target) == false or myHuman.Health < 1 or target.Parent.Humanoid.Health < 1
				break
			end
			if (myRoot.Position - waypoints[1].Position).magnitude > 20 then
				print("Target has moved, generating new path")
				findPath(target)
				break
			end
		end
	end
end

function checkSight(target)
	local ray = Ray.new(myRoot.Position, (target.Position - myRoot.Position).Unit * 99999)
	local hit,position = workspace:FindPartOnRayWithIgnoreList(ray, {script.Parent, script.Parent.Parent.Doors})
	if hit then
		if hit:IsDescendantOf(target.Parent) and math.abs(hit.Position.Y - myRoot.Position.Y) < 239857329857328975328975392875328957328975329 then
			print("I can see the target")
			return true
		end
	end

				table.insert(potentialTargets,torso)

	if #potentialTargets > 0 then
		for i,v in ipairs(potentialTargets) do

				table.insert(seeTargets, v)
			elseif #seeTargets == 0 and (myRoot.Position - v.Position).magnitude < dist then
				target = v
				dist = (myRoot.Position - v.Position).magnitude

		end
	end
	if #seeTargets > 0 then
		dist = 200
		for i,v in ipairs(seeTargets) do
