External Browser Authentication - Snowflake

Hi, I am having an issue using dbt in VS Code.

I have aligned my profiles.yml file in accordance with other team members. However, when I run a command in the terminal, dbt attempts to initiate a login request with my identity provider by opening a new browsing window to Snowflake (which is the intention as we use Snowflake as our data warehouse).

However, the new window does not open automatically as intended. There is the option to copy a link, from there entering the URL into the command window again. However, when I copy the link provided, it times out each time and eventually the page fails to load.

Here is a screenshot:

Any ideas around how I can get the window to open automatically and why this might be blocked ?
