SharePoint - Unable to create & delete Team site

Issue: Need to create a SharePoint site.

Users are trying to create a Team site (classic experience). After they  “create” the site, it never shows up. No errors, no nothing.

Both users have a shared admin account called “Shares” which we are trying to make the administrator of the site. We are also trying to create the site with that account. It is an Global Admin account.

User had a Team Site with that same name that they deleted, but it will not let us Permanently delete the site. They have done this before, so not sure why it’s not letting us permanently delete this one.

Solution:

Please let us while deleting Team Site you also deleted its Office 365 Groups?

Kindly refer to this article:

Also you may use following command to remove the site permanently from Recycle bin:

Remove-SPODeletedSite -Identity <site url>
