Sites that have subsites or certain apps can't be deleted SharePoint 2019

Question

In SharePoint 2019, I have a subsite that holds many subsites and when trying to delete the main subsite I got this error "Sites that have subsites or certain apps can't be deleted" 

Sorry, something went wrong
There was a problem deleting Web site "/subsite". Sites that have subsites or certain apps can't be deleted. Please try again after deleting all subsites and removing the apps.

Actually, I can't delete all subsites one by one, it's about 30 subsites, so I am looking for a PowerShell script that deletes all subsites under the parent site to avoid this error!

Solving: Sites that have subsites or certain apps can't be deleted in SharePoint 2019

It's a logical error, you can't delete the parent site until delete all subsites under it, and to solve this issue, you have to loop for each subsite under the main site then delete subsites using PowerShell.

To delete all subsites below the specific site, you have to do the following:

1. Open Windows PowerShell As Administrator.
2. Add PowerShell Snapin to Microsoft.SharePoint.
3. The use the below PowerShell script to delete all subsites under specific main site.

      {
         Write-host "Remove" $SubSite.Url
         Remove-SPWeb $SubSite -Confirm:$false
     }
