What's Wrong?

Platform: Claude Desktop (Windows) Operating System: Windows 11 Claude Desktop Version: Version 1.3109.0 (35cbf6) Subscription: Pro

Claude Desktop consistently opens to a completely blank/white screen and never renders any content. The app is unusable in this state. Most critically, Cowork — which I rely on for active job searching — is completely inaccessible. Every time the app launches, 9 Claude processes appear in Task Manager but nothing is displayed on screen.

What Should Happen?

The app should launch and render the UI normally, with all features including Cowork accessible and functional.

Error Messages/Logs

No error messages are displayed. The app window opens with a completely blank/white content area. No crash dialog or error output is shown.

Steps to Reproduce

  1. Install Claude Desktop on Windows
  2. Launch the app from the Start Menu or desktop shortcut
  3. App window opens but content area is entirely blank/white — no UI renders
  4. Open Task Manager — 9 Claude processes are running simultaneously
  5. Kill all 9 processes via Task Manager
  6. Relaunch the app
  7. Blank screen reappears immediately with 9 new processes spawning again

Additional Information

  • Multiple full uninstalls and reinstalls have had no effect whatsoever
  • No local app data folders are created on disk — %AppData%\Claude and %LocalAppData%\AnthropicClaude do not exist, suggesting the app is failing to initialise properly
  • Killing all 9 processes via Task Manager and relaunching reproduces the blank screen every time
  • This issue is blocking use of Cowork, which is essential to my workflow
  • Operating System: Windows [add your version here — e.g. Windows 10 or Windows 11]

extent analysis

TL;DR

The issue might be related to the app's failure to initialize properly, and a potential fix could involve investigating the app's data storage and initialization process.

Guidance

  • Investigate why the app's local data folders (%AppData%\Claude and %LocalAppData%\AnthropicClaude) are not being created, as this could indicate a problem with the app's initialization process.
  • Try checking the system's permissions and access control settings to ensure that the app has the necessary permissions to create these folders and write data to them.
  • Consider checking the Windows Event Viewer logs for any errors related to the app's launch and initialization process, as these might provide more insight into the issue.
  • Since multiple uninstalls and reinstalls have had no effect, it might be worth trying to manually delete any remaining app data or configuration files that could be causing the issue.

Notes

The issue seems to be specific to the Windows platform, and the fact that no error messages are displayed makes it harder to diagnose. The presence of 9 Claude processes in Task Manager suggests that the app is trying to launch, but something is preventing it from rendering the UI correctly.

Recommendation

Apply workaround: Given the lack of error messages and the app's failure to initialize properly, it might be worth trying to reset the app's configuration or data storage to see if that resolves the issue. However, without more information about the app's internal workings, it's difficult to provide a more specific solution.
