Running iOS apps causes runtime error for frameworks “code signature invalid”

问题

Every time I try to run this app it builds OK, and installs but as soon as it runs the app breaks and prints this error message. XCode 11 and iOS 13.

I've seen many similar posts on here and on App Developer forums about this problem but not one has an explanation or a valid fix. I've tried

Cleaning and building
Restarting XCode
Restarting Mac
Completely resetting Keychain
Verifying all Keychain certs Trust settings are on "Use System Defaults"
Factory resetting my Mac

UPDATE 1: It appears to be an issue with my iOS device. The app can start up on a simulator, but the simulator is not good for my development purposes so I need to make this work on my device. I recently updated my iPhone XR to iOS 13.3.1.

UPDATE 2: Found another group seeming to have the same issue https://github.com/flutter/flutter/issues/49504.

This is an issue with iOS 13.3.1. All dynamic frameworks being compiled to the newest release of iOS 13.3.1 are experiencing this issue when run on a personal provisioning profile/developer account. The solution, copied from jmagman from Github, is below.
