Windows Terminal version

1.23.10353

Windows build number

27788

Steps to reproduce

My computer pops up a Windows Terminal window upon startup, which becomes unresponsive and freezes. This has happened twice now, with the previous occurrence happening a few days ago. I attached to the process in VS, paused the program to check where it was blocked, and found that a lock is waiting and has never been notified within TerminalConnection.dll.

Some suggestions on solving this,

  1. Update your windows.
  2. Go to the call stack and analyze, it maybe you are having shared resources that multiple threads are trying to access simultaneously.
  3. Try repairing windows or re-setting the windows

I can confirm this is also happening for me on Windows 11 24H2, on version 1.21.10351.0 - with the exact same call stack according to x64dbg. It also happened to unfreeze itself after I closed a game that was open, possibly related to #18040.
