A clear description of what you expected to happen instead.
Permission lost when using Cloud Shell, it is working in Windows PowerShell

Is this specific to Cloud Shell? Yes, Windows PowerShell works

Please verify if the same issue can be reproduced by running the same tool outside Cloud Shell - for example,
by installing it on your own computer. If so, it is likely to be a bug in that tool or in the Azure service it communicates with,
not in Cloud Shell. Please file the issue with the appropriate project.

Interface information neither ttps://shell.azure.com nor https://portal.azure.com works

How are you accessing Cloud Shell - https://shell.azure.com, https://portal.azure.com, via Windows Terminal, or some other method?
If a browser, which Operating System and browser are you using? (ex. Edge on Windows 10)

Additional context

Does it work if you run 'az login' in Cloud Shell prior to running the command?
