Orphaned custom URL after renaming app in AI Studio

Hi team, I created an app named ‘remix A’ and published it using the custom URL ‘hogwartswizard.ai.studio’. After that, I renamed the app to ‘A’. The UI forced me to publish to a new link, and I completely lost access to the old ‘hogwartswizard.ai.studio’ URL on my dashboard. However, the old site is still running on Google’s servers. Since I am on the free Starter Tier, I have no GCP console access to delete this container. Please help me take down/delete the orphaned deployment for hogwartswizard.ai.studio. Thank you.
