What's Wrong?

After clicking the Code tab, the app briefly shows a "What's your next schedule?" UI (calendar/schedule loading screen) and then crashes within a few seconds. The window closes completely.

What Should Happen?

Environment

App version: Claude Desktop 1.3109.0 (MSIX: Claude_1.3109.0_x64__pzs8sxrjxfjjc)
Install path: C:\Program Files\WindowsApps\Claude_1.3109.0_x64__pzs8sxrjxfjjc
OS: Windows
Install method: Downloaded .exe installer from claude.ai/download (resulted in MSIX install)

What's wrong
After clicking the Code tab, the app briefly shows a "What's your next schedule?" UI (calendar/schedule loading screen) and then crashes within a few seconds. The window closes completely.

Steps to reproduce

Open Claude Desktop
Click the Code tab
A schedule/calendar loading UI briefly appears
App crashes and closes

What works fine

Chat tab: works normally
Cowork tab: works normally

Troubleshooting already attempted

Sign out and sign back in → crash persists
Updated to v1.3109.0 (officially marked as resolved) → crash persists
No Google Calendar or other connectors are connected

Expected behavior
Code tab should load normally without crashing.

Note
This issue persists even after the v1.3109.0 fix that was announced as resolved on status.claude.com. The fix may only apply to Win32 installations, not MSIX.

Update: Additional debugging findings

I've done extensive testing to narrow down the cause. Here's what I've ruled out:

Documents folder pointing to OneDrive path → not the cause
Virtual Machine Platform disabled → enabling it didn't help
D: drive project path → session content loads fine before crash
Persisted sessions (7 files) → cleared all sessions, same crash occurs
Session file size → files are only 400-500 bytes each

Key observations:

Two PCs with identical CPU, OS build, app version, and Claude Code CLI version. One works fine, one crashes. The working PC has no log folder under LocalCache\Roaming\Claude\.

All log entries up to the crash point are [info] level — no errors recorded. The crash occurs after the last log entry, suggesting the process terminates before the logger can capture it.

Crashpad generates a report (~33.9MB .dmp file) only on forced termination, not on normal exit. I can share this dump file privately if you can provide a secure upload channel, as it may contain personal information.

Would appreciate any guidance on next steps or a private channel to share the crash dump.
