Windows Terminal version

1.21.1272.0

Windows build number

10.0.22631.3527 x64

Other Software

Just Terminal Preview, crashes with any shell (tested cmd.exe, bash in Ubuntu in WSL2).

Steps to reproduce

  1. Open Windows Terminal Preview with your default shell
  2. Click the [v] menu, and select Settings to display the settings page
  3. Tear-off the Settings panel into its own window, making both settings and your shell visible
  4. Select any shell profile, click [Appearance >]
  5. Close the Settings tab, which closes its individual window.
  6. Wait ~30 seconds (could be longer apparently if focus is changed)
  7. Give the focus to some other app, then click on your shell panel to give it the focus again
  8. ?
  9. Profit!

I've crashed it 10 times using these steps, it works every single time.

Edit: I'm still trying to reduce the steps to the minimum required.

Expected Behavior

Windows Terminal should keep running

Actual Behavior

Windows Terminal freezes, its client area gets ghosty transparent, it receives the dreaded (Not Responding) suffix, and Dr. Watson comes along to put it out if its misery.
