Cannot delete Azure Virtual Network app-vnet stuck in Failed state after App Service VNet Integration cleanup

Hello,

I need help deleting a stuck Azure Virtual Network and Resource Group.

Subscription: d582ee2f---****-041527f00d79

Resource group: rg-genapp

Virtual Network: app-vnet

Subnet: app-integration-subnet

Region: France Central

Issue: The resource group deletion is stuck because the Virtual Network app-vnet is in Failed state.

The subnet app-integration-subnet was previously delegated to Microsoft.Web/serverFarms for App Service VNet Integration. The App Service has already been deleted.

I ran the cleanup command:

POST /subscriptions/{subscriptionId}/providers/Microsoft.Web/locations/francecentral/purgeUnusedVirtualNetworkIntegration?api-version=2024-04-01

Result:

{ "message": "Purged unused virtual network integration.", "swiftVirtualNetwork": null }

Current subnet state:

• provisioningState: Failed

delegations: Microsoft.Web/serverFarms

serviceAssociationLinks: null

ipConfigurations: null

privateEndpoints: null

Current VNet state:

provisioningState: Failed

I also tried:

Get-AzVirtualNetwork -ResourceGroupName rg-genapp -Name app-vnet | Set-AzVirtualNetwork

But it failed with:

VnetCannotGetUpdatedWhenDeletionWasAttemptedEarlier

Virtual Network app-vnet can not be updated when deletion was attempted earlier.

Other errors:

Subnet update returns:

SubnetCannotGetUpdatedWhenParentVnetDeletionWasAttemptedEarlier

VNet delete returns:

InternalServerError

Question: Is there any way to clear the stuck backend deletion/update state without opening a paid Azure support plan?Hello,
