Try signing in to the Account Console (https://accounts.azuredatabricks.net/login) using a user account with the appropriate permissions, rather than accessing it from the workspace.

If you are unable to sign in, the following resource might be helpful:
Known Issues – Unable to Login to Azure Databricks Account Console

If the issue persists, please share the error message displayed when attempting to sign in to the Account Console.
