What's Wrong?

## Problem
Claude Desktop closes/crashes silently within ~10-30 seconds of launching. No error appears in any log file — main.log,
claude.ai-web.log, or Windows Event Viewer. The process simply disappears.

The crash happens even without opening any project or sending any message. Claude Code CLI works perfectly fine.

## What was tried (all failed to fix)

  1. Reinstalled Claude Desktop (~10 times)
  2. Windows System Restore
  3. Wiped entire %APPDATA%\Claude\ directory
  4. Cleared GPU cache, IndexedDB, Session Storage, Local Storage, Crashpad
  5. Launched with --disable-gpu
  6. Removed all MCP servers from config
  7. Disabled all user-level hooks (settings.json)
  8. Disabled all project-level hooks (.claude/settings.local.json)
  9. Disabled all plugins (superpowers, skill-creator, claude-mem)
  10. Renamed project .claude/ directory
  11. Cleared persisted sessions
  12. Deleted orphaned cloud projects/environments
  13. Deleted VM bundles (partial 2.2GB rootfs.vhdx download)
  14. Disabled cowork/ccd scheduled tasks in preferences

## Observations from logs

  • main.log shows normal startup, no errors, then just stops writing (no crash/exit message)
  • Sentry error captured with no details: eventId: '4056f2c518a441a8969d03f27a647c92', type: 'Unknown', value: 'No message'
  • claude.ai-web.log shows recurring Internal error opening backing store for indexedDB.open and 404 errors for

model_configs/claude-opus-4-7[1m] and a deleted environment env_01AsyZrhTo9UMVkvu71QxzJ8

  • VM download of rootfs.vhdx (2233.9 MB) starts every launch and never completes
  • cowork_vm_node.log shows rootfs.vhdx missing on every launch cycle

## Trigger
Started after using a git worktree command in Cursor to upload a project to GitHub.

## Workaround
Claude Code CLI continues to work normally.

Error Messages/Logs

no error

Steps to Reproduce

● Here are the steps to reproduce — paste this:

## Steps to Reproduce

  1. Install Claude Desktop v1.6259.1 from Windows Store (MSIX) on Windows 11 Pro x64
  2. Launch the app — it opens normally, shows login screen
  3. Log in with Google auth — login succeeds, home screen appears
  4. Wait ~10-30 seconds — the app window closes silently with no error dialog

Additional context:

  • The crash happens even without navigating to any project or sending any message
  • main.log shows normal startup sequence then simply stops writing — no crash, no error, no exit message
  • No crash appears in Windows Event Viewer (Application log)
  • Sentry captures an empty error: eventId: '4056f2c518a441a8969d03f27a647c92', type: 'Unknown', value: 'No message'
  • claude.ai-web.log shows recurring errors:
  • Internal error opening backing store for indexedDB.open
  • 404 for model_configs/claude-opus-4-7[1m] (note: model ID has 4-7 not 4-6)
  • 404 for deleted environment env_01AsyZrhTo9UMVkvu71QxzJ8
  • VM download of rootfs.vhdx (2233.9 MB) starts on every launch, never completes before crash
  • Claude Code CLI (v2.1.128) works perfectly — only the Desktop Electron app crashes
  • Issue began after a git worktree operation in Cursor IDE

Exhaustive troubleshooting performed (all failed):
Reinstall (10x), Windows System Restore, wipe %APPDATA%\Claude\, clear GPU/IndexedDB/Session/Local Storage/Crashpad, --disable-gpu
launch, remove all MCP servers, disable all hooks (user + project level), disable all plugins, rename .claude/ directory, clear
persisted sessions, delete cloud projects/environments, delete VM bundles, disable cowork/ccd scheduled tasks.
