Windows Terminal version

1.24.2372.0

Windows build number

10.0.26100.0

Other Software

No response

Steps to reproduce

  1. Add the following nested command definition to the actions array in your settings.json file:
{
    "name": "Change font size…",
    "commands": [
        { "command": { "action": "adjustFontSize", "delta": 1 } },
        { "command": { "action": "adjustFontSize", "delta": -1 } },
        { "command": "resetFontSize" }
    ]
}
  1. Launch Windows Terminal.
  2. Open the Command Palette by pressing Ctrl+Shift+P.
  3. Select the newly created nested command ("Change font size…").
  4. The palette will now show the three sub-commands. Click the "Back" button at the top to return to the main list.
  5. Select the "Change font size…" command again.
  6. Observe that Windows Terminal crashes.

Expected Behavior

The Command Palette should successfully re-enter the nested command's sub-menu without crashing, allowing the user to select one of the sub-commands.

Actual Behavior

Windows Terminal crashes immediately upon the second attempt to enter the nested command menu.

Hmm.. we can't repro it here, but do you by chance have a second/non-English UI language set/?

No, the UI language is English, and the system is in English as well.

That's weird. I had my friend try it, and the same thing happened to him.
