Bitbucket sent an email to all its users, including mine:

> You currently have access to an empty Bitbucket Cloud workspace that will be removed. Please note that this action will not affect your ability to login and access your Bitbucket Cloud profile and collaborate in existing non‑empty workspaces and content hosted in them or one's you join/create in the future. After July 31st 2024, we will begin deleting all empty Bitbucket Cloud workspaces. If you are an admin of the workspace, create a project or repository to prevent this deletion.
