Hi @robbert-nlo,

2.64.0 is not the latest Azure CLI(2.65.0).

If you haven't already attempted to do so, please upgrade to the latest Azure CLI version by following https://learn.microsoft.com/en-us/cli/azure/update-azure-cli.

Just tested with 2.65.0, issue is still there.

Also, I haven't been able to reproduce this on Windows (x86), so this may be MacOS / ARM specific issue.
