Desktop v1.15.13 - "Failed to load sessions" / "Unexpected server error" after full clean reinstall #30751

Description

Description
OpenCode Desktop v1.15.13 fails to start with repeated "Failed to load sessions" and "Failed to reload" toasts showing "Unexpected server error. Check server logs for details." The UI loads but the local Bun server never starts.

Steps to reproduce

1. Install OpenCode Desktop v1.15.13 from https://opencode.ai/download (Windows)
2. Launch the app
3. Observe error toasts immediately

What I have already tried

• Fully uninstalled and reinstalled the app
• Deleted %USERPROFILE%\.local\share\opencode (session database)
• Deleted %USERPROFILE%\.cache\opencode
• Deleted %USERPROFILE%\.config\opencode\*.dat files
• Deleted %APPDATA%\ai.opencode.desktop files
• Added Windows Defender exclusion for the install folder
• Ran as Administrator
• Confirmed no bun.exe or node.exe running in Task Manager
• Confirmed WebView2 is already installed
• Tried opening a new empty folder as workspace — same error
• Cleared all possible config and cache folders

System info

• OS: Windows 11

Additional context

• The app was working previously but started failing after a session with a chrome-devtools MCP configuration
• The error persists even with no workspace / empty folder
• No opencode CLI installed globally
• The old opencode-ai/opencode repo is archived, so reporting here
