Error Message

When I try to use Claude Desktop I've gotten this error message at least 20 times between yesterday and today. I've reinstalled the workspace at least 15 times, reinstalled the app, restarted my computer several times. I literally cannot do any work in Cowork on my projects because the app is crashing and producing this error message. Any suggestions? I can't use Cowork at the claude.ai site, can I? And even if I did, the projects probably won't even connect with the Desktop app, which would be problematic for my book-writing projects. At the moment, Desktop is completely unusable. I'm on Mac if that helps, and I have the latest version of Claude Desktop.

extent analysis

TL;DR

The issue is likely related to a VM connection timeout error in Claude Desktop, and a potential workaround is to try troubleshooting the network connection or reinstalling the workspace.

Guidance

  • The error message indicates a VM connection timeout after 60 seconds, which could be related to network connectivity issues or problems with the Anthropic API.
  • Try checking the network connection and ensuring that it is stable before attempting to use Claude Desktop.
  • Reinstalling the workspace, as suggested in the error message, may also help resolve the issue.
  • If the problem persists, it may be worth trying to use the web version of Cowork on the claude.ai site to see if the issue is specific to the Desktop app.

Example

No code snippet is provided as the issue does not involve code.

Notes

The issue is reported as a regression, meaning it worked in a previous version, but the last working version is not specified. This information could be helpful in troubleshooting the issue.

Recommendation

Apply workaround: The user can try troubleshooting the network connection, reinstalling the workspace, or using the web version of Cowork to mitigate the issue, as the root cause is unclear and no clear fix is available.
