Windows: Open in apps fails with spawn [object Promise] ENOENT #26928

Describe the bug

On OpenCode Desktop for Windows, the Open in menu only works for File Explorer. Selecting any other configured app fails with this toast:

Request failed
Error invoking remote method 'open-path': Error: spawn [object Promise] ENOENT

This happens for VS Code, Cursor, Zed, PowerShell, and Sublime Text. File Explorer opens correctly.

This appears to be Windows-specific. The same workflow works on my Mac, and it also worked on this Windows machine sometime last week.

Reproduction steps

1. Open OpenCode Desktop on Windows.
2. Open the Open in dropdown.
3. Select VS Code, Cursor, Zed, PowerShell, or Sublime Text.
4. Observe the failure toast.
5. Select File Explorer from the same menu.
6. File Explorer opens successfully.

Expected behavior

OpenCode Desktop should launch the selected external app with the current path, the same way File Explorer works.

Actual behavior

All non-Explorer targets fail with:

Error invoking remote method 'open-path': Error: spawn [object Promise] ENOENT
