I think you need to log out from everywhere, log in again, and start creation in AWS Marketplace again, if it is already there you can cancel subscription if you haven't used it yet.

Avoid clicking free edition. It will not work with free.

If you can login to databricks console remove AWS marketplace payment method before starting again.

Refer to the deck linked in the video’s description (https://drive.google.com/file/d/1ovZd...) and check slide no. 16, titled “Linking AWS to your Databricks account.” That slide includes a note stating: “If you do not see a successful message, follow the instructions in Appendix IV (slide 45).”
