Cannot run Catalyst app on other devices?!?

I prepare a private project in Xcode, use Archive, Distribute/Copy, save the application somewhere. Copy it to my other computer, run.

Works perfectly with normal MacOS applications.

With Catalyst ones though it does not; whatever I try, all I get is “The application XXX cannot be opened”.

What do I do wrong and how to fix the problem? Thanks!
