Windows App worktrees stay stuck on "Fetching worktree details", and project chat cannot send the first manual message

What version of the Codex App are you using (From “About Codex” dialog)?

26.422.30944

What subscription do you have?

Pro

What platform is your computer?

Microsoft Windows NT 10.0.19045.0 x64

What issue are you seeing?

In Codex Windows App, the global Worktrees settings page is permanently stuck on:

• Fetching worktree details.

At the same time, project chat is unusable for manual input:

• I can open a project thread
• I can type into the message box
• when I click Send or press the send shortcut, the send button spins forever
• the first manual message never gets submitted

Important details:

• This happens even in a brand new empty project
• This also happens in existing repositories
• This still happens with a completely fresh Codex config directory
• This still happens after removing all projects from the app
• The issue is specific to the Windows App project mode

What still works:

• normal non-project chat works
• Codex CLI works on the same machine
• project automation can execute a simple manual "hello" successfully

Because of that, this does not look like a general model/provider outage. It looks more like the Windows App project/worktrees initialization is stuck, and project chat never becomes ready.

What steps can reproduce the bug?

1. Open Codex Windows App
2. Open any project, including:

• a brand new empty folder
• an existing Git repository

1. Try to send the first manual message in the project chat, for example hello
2. Observe that the send button spins forever and the message is never submitted
3. Open Settings -> Worktrees
4. Observe that the page stays stuck on:

• Fetching worktree details.

Additional reproduction notes:

• Reproduces with PowerShell, cmd.exe, and Git Bash as the shell
• Reproduces even after using a fresh Codex config directory
• Reproduces even after removing all projects from the app

What is the expected behavior?

_No response_

Additional information

Git on this machine appears healthy:

• where.exe git -> C:\Program Files\Git\cmd\git.exe
• git --version -> git version 2.50.1.windows.1
• git worktree list works normally
• Get-Command git points to the same Windows Git executable

So this does not appear to be caused by a missing or outdated Git installation.
