Crash with "Killed: 9" message

[interference-security]

I am trying to run fsmon on iOS 12.1.2 (iPhone 6S) jailbroken using Unc0ver. When running fsmon it returns error message Killed:9.

What I have already tried:
lipo and ldid (Source: https://medium.com/@felipejfc/the-ultimate-guide-for-live-debugging-apps-on-jailbroken-ios-12-4c5b48adf2fb)
On Mac: lipo -thin arm64 fsmon-ios -output fsmon-ios-arm64
On iOS: ldid -Sentity.xml fsmon-ios-arm64
