This variation is rather linked to faulty disk permission. In another variation of this issue, the app crashes instantly upon launching. The app may crash by going into a complete shut down when all the processes stop working completely, at most times leaving users with no clue as per what has gone wrong. In this state, the app’s window remains open, and the app’s dock icon still indicates that the app is still running, but the app does not respond to any keypress. If apps crash and unexpectedly quit on macOS 10.14, the app’s processes are in continuous procession but not completed, hence its functions are rendered unresponsive. Apps that crash and unexpectedly quit on macOS 10.14 are mostly third party apps. But normally, apps that are downloaded from the Apple App Store are the least susceptible to compatibility issues on the new MacOS. Apple’s updates can interfere with the operations of an app in various ways that can render the app or its extensions incompatible with the OS.

That implies that the issue mostly occurs either because the creators of the apps are yet to release app updates that recalibrate the app to make it compatible with the new OS requirements, or that the user is yet to install the released app updates. These issues have been heavily-linked to app incompatibility issues on the new MacOS update.
