Team Foundation server setup-delete a project

A project is created for Team Foundation server!
The deleted project cannot be found.
Only commands can be used

Tfsdeleteproject [/q] [/teamfoundationserver: servername] [/Force] project name

Tfsadmin permission is required!
What's more strange is that

When the client is added to the TFS Server Admin, project creation will be interrupted.

The shreapoint error is reported.

If the project fails but cannot be created with the same name, an error is returned for a project with the same name.

You cannot find this project after you run the command to delete it.
