OpenCode Desktop 1.18.4 hangs indefinitely during first-launch onboarding on Windows

Description

I installed OpenCode Desktop 1.18.4 on Windows 11 using Scoop.

The installation completed successfully, but when I launch the application it remains stuck on the loading screen indefinitely.

OpenCode CLI works correctly on the same machine. The issue only affects the Desktop application.

Environment

• Windows 11 Pro
• OpenCode Desktop v1.18.4
• Installed via Scoop
• No plugins installed

Steps to reproduce

1. Install OpenCode Desktop using Scoop.
2. Launch OpenCode Desktop.
3. Wait for the onboarding/loading screen.

Expected behaviour

The application completes onboarding and loads the main window.

Actual behaviour

The application remains stuck on the loading screen and never progresses.

Relevant logs

Additional context

I deleted %APPDATA%\ai.opencode.desktop and reinstalled, but the behaviour was unchanged.

DevTools shows no errors in the Console.

Network requests all return 200 or 204 responses.

The application never progresses beyond onboarding.
