debugFeatures crashes on opening debug tab

[inphobia]

Windows Terminal version

1.11.3471.0

Windows build number

19043.1415

Other Software

not relevant, crashing on opening any tab.

Steps to reproduce

• enable "debugFeatures": true, via edeting the config json
• restart windows terminal to activate it
• open a tab while holding left and right alt (on my keyboard - azerty be period layout, right alt is altgr no idea if that matters)

does not matter if the tab you open is from the dropdown list or via the "+" button. opening it via the shortcut ctrl+shift+t does nothing.

Expected Behavior

openes a new tab with a debug window. or at least does not crash.

it wasn't quite clear if release builds of wt can even enable this feature.

Actual Behavior

hangs for a few seconds, the crashes wt and all open tabs. (program just closs).

does work in current preview of wt.

eventlog shows this, dunno if there's any other debugging output to provide:

site note, also tested it with no "debugFeatures": true,

then alt left+right & mouseclick just open a new sidetab.

@inphobia "debugFeatures": true is a hit-and-miss with each release. It works with the Windows Terminal Preview Version: 1.12.3472.0

The only issue is debug pane not closing when exiting the tab, even though it exits with code zero:

It could be by design!
