Originally created by @DHowett on GitHub (Apr 19, 2023).

Originally assigned to: @zadjii-msft on GitHub.

At least 1x on my dev box, I observed the following:

  • Main thread is crashing in TerminalWindow::UpdateSettings because _root is nullptr, while trying to call _root->Dispatcher().
  • The window thread is actively constructing the UI and has not yet assigned _root.

Boom
