MacOS installer app can't be opened directly on MacOS 13

[Xiione]

MacOS 13.6.3
Below is what the app looks like in Finder.

Below is the dialog that appears when I try to open it in Finder.

The moonlight-installer executable itself can still be opened fine by going into the package contents in Finder or by running it via command line.
