Desktop crashes repeatedly with NotFoundError after task completion (non-git directory, 1.2GB DB) #26122

Description

OpenCode Desktop crashes repeatedly with service=server error=NotFoundError failed after task completion. The CLI backend (opencode.exe) remains unaffected — only the Desktop (Electron) GUI crashes and auto-restarts.

Pattern: Task completes → Desktop crashes → restarts → crashes again within 3-6 seconds → eventually stabilizes after a few cycles.

Today alone the Desktop has restarted 8+ times following this pattern.

Environment

• OpenCode Desktop: Latest (installed 2026-05-07, anomalyco/opencode via electron-updater)
• CLI: opencode.exe from ~/.opencode/bin/
• OS: Windows 11
• Working directory: D:\yhl10000 (NOT a git repository)
• Database size: opencode.db = 1.2 GB + WAL 6.3 MB
• DB location: C:\Users\hoyu\.local\share\opencode\opencode.db
• DB created: 2026-02-24 (3 months of accumulated session data)

Error Logs

Every crash log (~/.local/share/opencode/log/) ends identically:

ERROR 2026-05-07T04:19:15 +3105ms service=server error=NotFoundError failed
ERROR 2026-05-07T04:19:15 +9ms service=server error=NotFoundError failed
ERROR 2026-05-07T04:19:16 +353ms service=server error=NotFoundError failed
(log ends = process exits)

Additional errors seen on startup:

ERROR service=plugin.copilot error=The operation was aborted due to timeout failed to fetch copilot models
ERROR service=mcp clientName=azure_mcp error=MCP error -32601: Method 'prompts/list' is not available. failed to get prompts

Steps to Reproduce

1. Run OpenCode Desktop in a non-git directory (no .git folder)
2. Accumulate a large session database (1+ GB over weeks of usage)
3. Execute a task that produces substantial output (e.g., file generation, multi-tool operations)
4. Task completes → Desktop crashes
5. Desktop auto-restarts but crashes again within seconds (NotFoundError on session restore)
6. After 2-3 restart cycles, eventually stabilizes

Root Cause Analysis

Based on log analysis:

• The NotFoundError occurs during Desktop's service=server request handling
• It appears the Desktop tries to restore/reload the last session after restart
• Since the working directory is NOT a git repo, projectID resolves to "global"
• The session may have been stored under a different project scope, or the 1.2GB DB causes lookup failures
• The error is unhandled — it crashes the app instead of gracefully recovering

Key Observations

Expected Behavior

1. NotFoundError should be caught gracefully — clear stale session reference and recover to project view
2. Desktop should not crash-loop when session restore fails
3. Large databases (1GB+) should not cause session lookup failures
