Environment

Windows build number: Microsoft Windows [Version 10.0.18363.836]
Windows Terminal version (if applicable): 1.0.1401.0

Any other software?: Narrator, the version which comes with this windows build

Steps to reproduce

• Start Narrator using Win+Ctrl+Enter
• Open the Windows Terminal app
  • Make sure the Narrator cursor (blue box) is on the terminal cursor, and/or that Narrator says "editing" as part of the information when you navigate to the terminal window (if Narrator is not focused on the correct place in the terminal window, alt-tabbing away and back should fix it).
• Activate scan mode with Caps+Space (Narrator will say "scan")
• Press the down arrow key (Narrator will say "title bar")
  • If Narrator does not announce "title bar", it may be further down in the UI tree. Keep pressing the down arrow until you reach it
• Press the up arrow key, and the Windows Terminal app crashes

Expected behavior

I would expect the terminal app not to crash, and for Narrator focus to return to the edit box.

Actual behavior

The terminal app crashes.
