Originally created by @daxian-dbw on GitHub (Dec 1, 2022).

Windows Terminal version

1.16.2642.0

Windows build number

10.0.22621.819

Other Software

No response

Steps to reproduce

There is no consistent reproduction. It happens often enough, usually after logged in Windows after logging out for a while or after waking up the machine from sleep.

Dump file: The dump file can be downloaded from https://1drv.ms/u/s!AvrzkkkRHNSrhic-ffAuUGxdtbc_?e=0LhRhk

When this happens, I cannot open another Windows Terminal, but have to forcefully close the one that is hanging.
Below is a screenshot of the Windows Terminal when it happens. Please note the small close button highlighted in the red circle. This small close button stays even after forcefully closing the Windows Terminal process, and I have to click on it to make that button disappear.

Expected Behavior

Windows Terminal should not hang

Actual Behavior

It hangs from time to time.

main thread is in OnDwpSysCommand north of DefWndProc

message, wparam, lparam= 0x112, 0x0f020, 0 -> WM_SYSCOMMAND, SC_MINIMIZE

Never seen one of these before:

That small close button is a conhost process, with a window that should not be visible. Next time this happens, there should be an openconsole.exe in the Terminal process tree. Mind grabbing a dump of that?
