ArcGIS Pro 2.5: Deleting a subtype for line utility network feature fails and ends up with 002140 error (the subtype is required by utility network),

Despite the fact that the topology is not enabled yet, deleting a subtype for line utility network feature fails and ends up with 002140 error (the subtype is required by utility network)

Is this by design?
