App cannot launch on macOS Sonoma

[Cellomaster87]

I have tried this several times, plus erasing the app, downloading it again, and trying once more.
The app doesn't launch, or crashes during launch, on macOS Sonoma.
I may have accidentally chosen "Don't Allow" on the request to access "SystemEvents.app" in the beginning.
Now I do not know where to give that permission back, if that is the issue.
What can I do for this?

You can check the various options in System Settings.app → Privacy & Security and see whether the app shows up there. I don't however see, why the EPUB-Checker should require access to any of these permissions. So if this manages to fix your issue, please let me know.

Sadly there is no trace of the app in any page of System Settings > Privacy & Security
I have tried to download it again, both the app and the DMG.
I moved them to the Applications folder and then tried to launch them.
I hit Open when prompted to accept an app downloaded from the Internet and the Finder's window flashed briefly, then nothing. The app appeared in the Recent Apps section of the Dock, but won't launch.
I have no idea what to do.
