.APP does not open on Mac.

I am referencing this tutorial. After following the tutorial I used PyInstaller on a simple Hello World app and shared the .DMG file with another user on a Mac, their Mac displays the message 'Application x can't be opened.' Additionally, when I run the example disk image provided by the PyQt6 packaging tutorial on my Mac, it shows the message 'Application has been damaged.' Am I missing something? I'm using a 2020 Mac Mini M1 running Sonoma as the OS, the other user is running the same setup. Screenshots are included below:
