Hi N Kulkarni
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.
Check that the Recovery Services Vault isn't holding any backup data. Restore point collections are usually linked to the vault, and if it’s still active, it might stop you from deleting the restore point.
Try to delete the whole restore point collection connected to the lingering restore point. You can usually find it in the resource group for your Azure Backup instance.
If there are active sessions or shared access signatures (SAS) connected to the restore point, you might need to revoke them before you can delete it. You can do this in the Azure Portal or by using Azure CLI commands.
If regular deletion methods don't work, you can use Azure Resource Explorer to find and manually delete the restore point resource.
In some situations, recreating the resource group that held the restore point collection might help you remove it successfully.
