Hello,
Welcome to Microsoft Q&A,
The YouTube video linked in the Azure Quickstart Center is marked "Private" on YouTube or archived. Videos marked "Private" cannot be watched unless you are specifically invited by the video owner (even if you have the link). Multiple users have reported this recently on Microsoft forums and Reddit after subscribing. Ignore the broken videos and continue learning through the Azure Portal's "Learn" section. Access alternative Quickstart tutorials directly at Microsoft Learn. Use the Azure Video Series playlist here: Azure Video Library (Public)Please Upvote and accept the answer if it helps!!
