Hi Yamen M,
Thank you for reaching out to us on the Microsoft Q&A forum.
Better whenever you start the lab don't open other windows until the lab completes.
Sometimes, simply refreshing the page can fix temporary lab issues. If it persists, close and reopen your browser. Clearing browser history or using incognito mode may help resolve cached or extension-related problems.
We tested it on our end, and it's working fine. Please refer to the screenshot below.
