Description

Attempting to package for TvOS on Mac without a signing key produces an error in the message log informing the user of the missing key. The error has a link to a tutorial on how to resolve it. Clicking the link on mac produces and ensure followed by a crash. Looking in crash reporter this is also being seen in 4.16 in the wild.

I haven't been able to reproduce the issue on PC due to the lack of signing key error message.

Steps to Reproduce
  1. Open QAGame
  2. File>Package Project>TvOS
  3. Click "Tutorial" in the message log next to the error "Signing key not found..."

Result:
Observe a crash as the tutorial attempts to load
