    Using the T-SQL debugger against something else than your local instance, requires quite a bit of red tape. Personally, it is soon twenty years I stopped using the debugger. I spent more time to get it working than I won in productivity.

    And since the debugger mainly works with variables, and the most interesting action goes on in tables, it is of limited use anyway.

    I used PRINT, SELECT and occasionally sp_sqltrace.

    Hi @D D ,

    Windows Firewall rules must be configured to enable Transact-SQL debugging.

    Try to start it by right clicking and selecting run as administrator, which is one of Requirements for Starting the Debugger.
    BTW, this feature works with SSMS version 17.9.1 and earlier.

    Best regards,
