Thanks for reaching here! As you mentioned you cleaned some services you didn’t use. Just wanted to know which services you have deleted to help you better on this.
Also you may want to know that if you have accidently deleted your app in Azure App Service, you can restore it using the commands from the Az PowerShell module. With some below limitation.
• Deleted apps are purged from the system 30 days after the initial deletion. After an app is purged, it can't be recovered.
• Undelete functionality isn't supported for the Consumption plan.
• Apps Service apps running in an App Service Environment don't support snapshots. Therefore, undelete functionality and clone functionality aren't supported for App Service apps running in an App Service Environment.
You may want to refer below document link for more details on this https://learn.microsoft.com/en-us/azure/app-service/app-service-undelete
Looking forward to help you on this.
