Unable to permanently delete Azure DevOps Server 2020 project

I deleted two projects in Azure DevOps Server 2020 using the collection settings -> projects screen. I know DevOps Server soft deletes projects and they are listed when you click on 'View recently deleted projects'.

I want to permanently delete the two projects. I've tried deleting the two projects using Azure CLI with the command az devops project delete --id [project id] and I keep getting the error VS800075: The project with id '8f0d8b14-837b-47aa-802c-aac2*********' does not exist, or you do not have permission to access it. I've tried inputting the id without dashes and get the same error.

I've tried to use TFSDeleteProject but it's not available with my version of Visual Studio, 2022. I think it might be only available with older versions.

I've also tried to delete the two projects using the Azure DevOps REST Api and I get a similar error:

{"$id":"1","innerException":null,"message":"VS800075: The project with id
     | '8f0d8b14-837b-47aa-802c-*************' does not exist, or you do not have permission to access
     | it.","typeName":"Microsoft.TeamFoundation.Core.WebApi.ProjectDoesNotExistException,
     | Microsoft.TeamFoundation.Core.WebApi","typeKey":"ProjectDoesNotExistException","errorCode":0,"eventId":3000}

I've regenerated my security token in DevOps and made sure I have full permissions. Is there a way to permanently delete a project in DevOps Server 2020?

If you don't want to wait 28 days until it will permanently deleted you need to delete the project from the Azure DevOps Administration Console:
