Mac App Store Validation bugged?

So…

I am using Unity 2018.3.7f1.

I want to try and upload my app into the mac app store but for that i need Mac App Store Validation checked according to https://docs.unity3d.com/Manual/HOWTO-PortToAppleMacStore.html,

When building the app with the option checked the file comes out damaged and cannot be opened, when building the app with the option unchecked then the app opens up.

Why is this happening? whats going on?

Yep, it’s broken.
