Azure blob storage copy doesn't work since Azure CLI 2.66+

Describe the bug

#29964
Hi @calvinhzy, @yonzhan,

I wanted to bring to your attention an issue we've been experiencing with the Azure DevOps CLI since the release of version 2.66. Our task to copy blobs no longer works.

Could you please provide some insights into what might have changed in version 2.66 that could be causing this issue? Any guidance or suggestions to resolve this would be greatly appreciated.

Thank you for your assistance!

@SymbioticKilla It is possible that the user authorization was not setup fully. Below example shows the command working for copying between two containers within the same storage account. Can you check the logged in user's access control?

Thanks! We will check it with your access permissions. We use Storage Blob Data Contributor only.
Were there any changes in this area? Because it was working before 2.66.
