Hi Stephen Lee,
Thank you for reaching out to us on Microsoft Q&A forum.
We see that you are facing an issue during your training on Microsoft Learn path as mentioned below:
- Section: AZ-104: Prerequisites for Azure administrators - Training | Microsoft Learn
- Module: Configure Azure resources with tools - Training | Microsoft Learn
- Unit 5 of 9: Interactive lab simulation (Azure PowerShell) - Training | Microsoft Learn
I've just tested the simulation on my end, and it seems to be working fine. To assist you more effectively, in this case, I suggest that you kindly follow some basic troubleshooting steps.
- Try it in another browser (Google Chrome, Mozilla Firefox & Microsoft edge) and please ensure that your browser is up to date.
- Have you tried clearing your browser cache and cookies.
- Are there any browser extensions enabled? If so, could you try disabling them and attempting to load the simulation again.
- Do you have any security software or firewall settings that might be affecting the loading process.
- Have you tried accessing the simulation from a different network or device.
For your reference, I am sharing the screenshot as below:
