Error Messages/Logs

Failed to start Claude's workspaceVM service not running. The service failed to start.Restarting Claude or your computer sometimes resolves this. If it persists, you can reinstall the workspace or share your debug logs to help us improve. Research pointed to this,,The DCOM error with those exact GUIDs is the Hyper-V COM permission issue. The Claude MSIX app container doesn't have permission to activate the Hyper-V interface it needs to start the VM.  This matches exactly what we found in the GitHub bug reports earlier. Unfortunately this is a known bug with no official fix yet from Anthropic — the MSIX sandbox is blocking the DCOM activation and the APPID {15C20B67-12E7-4BB6-92BB-7AFF07997402} isn't visible in Component Services so you can't manually fix the permissions.
