@i42-dh Thanks for sharing the details. Looks like you don't have the right to perform the registration of the resource Microsoft.Storage as I can see 403 error for the storage resource registration. As this may be the first time someone is trying to create the storage resource or someone unregistered the Microsoft.Storage on the subscription so portal will try to register the resource on your subscription but as you don't have the permission the operation is getting failed. Please navigate to your subscription and verify under Resource Providers whether Microsoft.Storage is registered or not. If it is not registered, then you need to reach out to the admin of your subscription to register the necessary resources in the new subscription. Once you have registered with the Microsoft.Storage
resource provider then retry the operation again to confirm if you still observe the issue.
For more details, please refer to this document for registering the resource provider.
