Steps to reproduce:

1. Open Windows Terminal.
2. Ensure that Settings -> Startup -> New instance behavior is set to Create a new window.
3. Launch another instance of Windows Terminal.
4. Close one of these two instances with any method you prefer (either with CTRL + Shift + W, or with Alt + F4, or by typing exit, or by activating the standard button with object navigation).

Actual behavior:

NVDA freezes for a random time (from 2 seconds to 1 minute). Moreover, after unfreeze, it hangs again when you try to activate the remaining Terminal window.

Expected behavior:

No freezes.

NVDA logs, crash dumps and other attachments:

A debug log demonstrating the issue is attached. First, I reproduce the problem using CTRL + Shift + W keystroke for window closing; next, Alt + F4 is tested.
