What's Wrong?

Claude tried to troubleshoot this issue and created this write up after not being able to solve it. It may be multiple issues, but it believes it is one root cause so warrants a single bug report.

To be clear I initially had this installed today and working as expected. It was only once I shut it down and reopened that I noticed the Cowork tab was missing along with my chat history for 3 apps that I prototyped (although the projects still exist in directories on my PC).

The Cowork tab is permanently missing despite being on a Pro plan, and session history is not persisting. A "validation_failed" error appears briefly on every fresh install. This survives multiple complete uninstall/reinstall cycles. I am not a developer — I am a regular Pro user and would appreciate a plain English explanation in any response.

What Should Happen?

1. The Cowork tab should appear for Pro plan users.
2. Session history should persist across launches.
3. Marketplace and Cowork initialization should retry after successful login if the initial attempt fails.

Error Messages/Logs

From main.log — these fire BEFORE login is complete:

[account] Account details not yet available, waiting for IPC...

[remoteMarketplaceMigration] marketplace_migration.paths_unavailable 
err=Error: No active account/org for marketplace operations

[remoteUploadsMigration] upload_migration.paths_unavailable 
err=Error: No active account/org for marketplace operations

[account] User logged out during IPC wait, stopping early

[LocalSessionManager] Cannot initialize sessions: accountId=null, 
orgId=null. Keeping existing sessions.

[LocalSessionManager] Session storage directory does not exist yet, 
skipping load: C:\Users\erw\AppData\Roaming\Claude\claude-code-sessions\...

Login SUCCEEDS shortly after but Cowork and sessions never reinitialize:
claude.ai account active and logged in

Steps to Reproduce

1. Fresh install Claude Desktop on Windows (MSIX package)
2. Launch and log in with Pro account
3. Observe "validation_failed" toast briefly appearing top right after login
4. Cowork tab never appears
5. Open main.log — "No active account/org" errors appear at 18:41:07,

successful login at 18:41:22, nothing reinitializes after

Claude Model

Not sure / Multiple models

Is this a regression?

Yes, this worked in a previous version

Last Working Version

Unknown — issue was already present before I noticed it was gone, but it was the exact same installer so had to be the same. Previously had Chat, Code, and Cowork tabs. Now only Chat and Code visible.

Claude Code Version

Additional Information

The app installs as an MSIX package which virtualizes file writes. App data ends up at:
C:\Users\erw\AppData\Local\Packages\Claude_pzs8sxrjxfjjc\LocalCache\Roaming\Claude\

instead of the standard:
C:\Users\erw\AppData\Roaming\Claude\

This caused significant confusion during troubleshooting — standard AppData locations appeared empty. Better documentation of MSIX data locations would help users and support staff diagnose issues like this in the future.
