extent analysis

TL;DR

The issue might be related to the yukonSilver module being marked as unsupported, and the Cowork tab not appearing in the desktop app.

Guidance

  • Check the logs for any errors related to the yukonSilver module and the Cowork tab.
  • Verify that the yukonSilver module is properly configured and enabled in the Claude Code settings.
  • Try loading the vmClient module manually to see if it resolves the issue.
  • Review the version history to identify when the regression occurred and check for any changes related to the yukonSilver module or Cowork tab.

Example

No code example is provided as the issue seems to be related to configuration or module loading.

Notes

The issue is reported as a regression, which suggests that it worked in a previous version. However, the last working version is not specified. The provided logs show repeated attempts to load the vmClient module, but the issue persists.

Recommendation

Apply workaround: Try manually loading the vmClient module or checking the configuration of the yukonSilver module to see if it resolves the issue, as the root cause is unclear without further information.
