Thank you for opening this issue, we will look into it.

It could be possible that the az command is broken.

1. Where are you running Azure CLI, Windows, Linux or MacOS?
2. Which shell are you using?
3. Could you share a screenshot of what you are seeing?

I had the same issue.
I reinstalled Azure CLI, tried different PowerShell consoles, and updated PowerShell to the latest version.
However, the problem persisted.

There was nothing related in the EventLog.
OS: Windows 11 with the latest updates.

The issue, as it turns out, was with my system (cmd.exe). After some Windows updates, it stopped working as it should have (CMD exited immediately after running).

I fixed it by executing the following command:
%SystemRoot%\System32\reg.exe DELETE "HKCU\Software\Microsoft\Command Processor" /v AutoRun /f

PS: I think az commands should be a bit more informative in similar cases
