Steps to Reproduce
Start the server using opencode serve.

Open the UI in a browser (tried Incognito mode to bypass cache).

The application fails to load, showing the error modal immediately.

Additional Context
The error was initially suspected to be related to recursive symlinks or complex file structures in the workspace. However, the issue remains even when pointed to a completely empty directory using WorkingDirectory in the Systemd unit. This suggests a possible infinite loop in the frontend asset (index-Bj9zfj-u.js) during the initial state hydration or component rendering.

    Same error on macOS

    I'm experiencing the exact same issue when trying to open the web UI:

    RangeError: Maximum call stack size exceeded

    at yr (http://localhost:4096/assets/index-Bj9zfj-u.js:2:8186)

    Environment:

    • OS: macOS (darwin)
    • Same asset file: index-Bj9zfj-u.js
    • Same stack trace pattern showing recursive calls between yr and X5 functions

    This confirms the issue is not specific to Linux/Ubuntu and affects multiple platforms.
