Original Pull Request: https://github.com/microsoft/terminal/pull/11428

State: closed
Merged: Yes

CascadiaSettings is default constructed when human readable error messages are
returned. Even in such cases we need to ensure that all fields are properly
initialized, as a caller might decide to call a GlobalSettings getter.
Thus a crash occurred whenever a user was hot-reloading their settings file with
invalid JSON as other code then tried to compare the GlobalSettings().

PR Checklist

  • I work here
  • Tests added/passed

Validation Steps Performed

  • Start Windows Terminal and ensure the settings load fine
  • Add "commandline": 123 to any of the generated profiles in settings.json
  • The application doesn't crash and shows a warning message
