• I also followed the same link that you have posted in your question and entered the values as below to get the access token and the refresh token for the Authorization code with PKCE request through Postman and it was successful as it returned me the refresh token as well as the access token. I also gave the scope of the application created the admin consent for accessing the application’s API further which I also stopped getting any issues in Postman. Also, you can clear the cookies any time whenever you use the Postman for getting any new tokens through the Authorization code with PKCE method. Though, it was good for you that when you restarted the Postman application, it successfully worked. It might be because your Postman application was pending for a restart post background application updates.
