    The page for the first programming tutorial (beyond "Unity Essentials" which is very basic) keeps crashing.

    URL: https://learn.unity.com/project/unit-1-driving-simulation

    I've tried in Firefox and Chrome, and have tried in incognito windows with no cookies or extensions.

    In the browser console I get this error and stack trace:

    Code (JavaScript):
    1. TypeError: null has no properties

    I also experience the same problem with Firefox 107.0

    It's a known issue that most of the official tutorial projects on here are out of date and don't work, it's unlikely the admins will do anything though.

    That's odd. I click on the link and see the page and can play the overview video. You might flush the browser cache if you haven't already.

    It looks like they've fixed the issue now. The page has changed, and it doesn't disappear with an error anymore.

    They seem to be actively working on these pages; I've noticed a few of the tutorials have moved around since I started doing them just a few weeks ago.
