After updating to the latest Azure CLI (2.22.0) for Windows 10, I am now seeing the same error as others have reported:<\/p>\n\n\n\n

Any command such as “az bicep version” is producing the following error:<\/p>\n\n\n\n

The command failed with an unexpected error.
Here is the traceback and detailed error:
type object 'datetime.datetime' has no attribute 'fromisoformat'

Is there a temp workaround?<\/h3>\n\n\n\n

One of the workarounds is to uninstalled Azure CLI 2.22.0 , and then install the prior version 2.21.0. You could confirm 2.21.0 version is working for you by running the same command.
<\/p>\n\n\n\n

Hope this will be helpful for you, as i faced with this issue hours before my demo to #GlobalAzure 2021 \ud83d\ude10 <\/p>\n
