Description

When I run the self-hosted web UI against a local OpenCode server, the page can stay on the loading screen indefinitely. I also hit crashes in the session/workspace UI when some session path or diff file values are missing.

Plugins

None

OpenCode version

• source-built dev binary during investigation: 0.0.0-dev-202604100729
• also reproduced against the packaged Windows install before switching to a source build for debugging

Steps to reproduce

1. Start a local OpenCode server and open the self-hosted web UI in the browser.
2. Keep a previously saved default server URL in browser storage, or load session/workspace data that contains missing directory / diff.file values.
3. Open the app or a session page.
4. Observe that the app can stay on the loading screen, or the session/workspace tree can crash while normalizing paths.
