Original Pull Request: https://github.com/microsoft/terminal/pull/4505

State: closed
Merged: Yes

This fixes a crash caused by Narrator starting before terminal.

Fixes #2907.

For context,

// We must initialize the main thread as a single-threaded apartment before
// constructing any Xaml objects. Failing to do so will cause some issues
// in accessibility somewhere down the line when a UIAutomation object will
// be queried on the wrong thread at the wrong time.
// We used to initialize as STA only _after_ initializing the application
// host, which loaded the settings. The settings needed to be loaded in MTA
// because we were using the Windows.Storage APIs. Since we're no longer
// doing that, we can safely init as STA before any WinRT dispatches.
