get workspace failed azuremlsdk - AuthenticationException

I have created a workspace in our azure environment and try to run this code:

library(azuremlsdk)

ws <- get_workspace(
    name = "someworkspace", 
    subscription_id = "si1", 
    resource_group ="rg1"
)

Some interactive authenticator opens in my browser, which I think is intended behaviour as I have no tenantdid. However, I get this:

Performing interactive authentication. Please follow the instructions on the terminal.
Note, we have launched a browser for you to login. For old experience with device code, use "az login --use-device-code"
You have logged in. Now let us find all the subscriptions to which you have access...
Interactive authentication successfully completed.

    }
}

I also tried:

az login

This works fine. So for me all this is very confusing!

So I tried the same in Python and had a similar error and came across this:

Downgrading:

 PyJWT 

helped. The bizarre world of open source and its web of interdependencies!
