Time Attack Racer Tutorial 6 checkpoint doesnt spawn after lap is done

After I finished the first lap on my Time Attack Racer Tutorial the first checkpoint doesn’t spawn again. I checked my script but that seemed OK. If anyone can help that would be appreciated.

In my case, even the first checkpoint doesn’t appear. Hence the next ones can’t appear as well.
Did you find a solution to your problem? Do you have any idea about how I should solve my issue

I think it was a version mismatch however I stopped using these tutorials in for virtus learning hub. I’ve been using those ever since and they are great!
