Ionic app launches then crashes with ios 12.4 update


I have a number of apps that are currently built with ionic 3.

cli packages: (/Users/lester/.nvm/versions/node/v8.11.1/lib/node_modules)

    @ionic/cli-utils  : 1.19.2
    ionic (Ionic CLI) : 3.20.0

global packages:

    cordova (Cordova CLI) : 8.0.0 

local packages:

    @ionic/app-scripts : 3.2.3
    Cordova Platforms  : android 8.0.0 ios 5.0.1
    Ionic Framework    : ionic-angular 3.9.8


    ios-deploy : 1.9.2 
    ios-sim    : 8.0.1 
    Node       : v8.11.1
    npm        : 6.0.0 
    OS         : macOS High Sierra
    Xcode      : Xcode 10.1 Build version 10B61

What I am seeing on some Apple devices is that once the phone/tablet is updated to ios 12.4 that the apps will attempt to launch. I then see the initial screen for a few seconds before it disappears.

If I delete the app, download, and install from the app store it will then work again.

Has anyone else seen this?
