What issue are you seeing?

After switching Codex Desktop Agent Environment from Windows Native to WSL, I can no longer create projects.

The UI only shows:

Failed to create project

There are no additional details in the UI.

The Codex Desktop logs contain:

[host-app-server-projects] Local app-server project migration failed
errorMessage="Invalid request: AbsolutePathBuf deserialized without a base path"

### What steps can reproduce the bug?

1. Use Codex Desktop on Windows with **Agent Environment = Windows Native**.
2. Create and use several local projects with Windows paths (e.g. `C:\Work\Android\...`).
3. Change **Agent Environment** from **Windows Native** to **WSL**.
4. Restart Codex Desktop.
5. Try to create a new project.
6. Codex Desktop shows **"Failed to create project"** without any additional explanation.

The logs show:

`[host-app-server-projects] Local app-server project migration failed errorMessage="Invalid request: AbsolutePathBuf deserialized without a base path"`

The issue started specifically after migrating the Agent Environment from Windows Native to WSL.

### What is the expected behavior?

_No response_

### Additional information

_No response_

Start with the Codex Desktop local app-server project migration path and the log message about AbsolutePathBuf being deserialized without a base path. Reproduce the Windows Native to WSL switch using the listed steps, then verify that creating a project succeeds after migration without the failure message.
