Can I downgrade my iPhone from iOS 18.5 to iOS 18.4?

One of my regularly used apps, OMRON Connect, quit working when 18.5 was installed. The app works fine on my iPad, but crashes on startup on my phone, iPhone 12.

Apple does not allow downgrading or reverting your iPhone's iOS. If this third-party app is not performing as expected, please try to uninstall the app, perform a Forced Restart, then re-install the app. If all else fails, you will need to contact the App Developers of this app and report the issue to them as Apple cannot do anything about it.
