What's Wrong?

When I want to work in Caude cowork or Claude Code, this is the message I get:

Impossible de démarrer l'espace de travail de Claude.
VM service not running. The service failed to start.
Redémarrer Claude ou votre ordinateur résout parfois ce problème. Si cela persiste, vous pouvez réinstaller l'espace de travail ou partager vos journaux de débogage pour nous aider à nous améliorer.

Cowork worked yesterday, but today it doesn't work anymore.

What Should Happen?

Claude should open the working space correctly
