When it fails to start, Claude Code shows \"Failed to initialize sandbox\" and resets its state. That reset now also clears the record that the sandbox had finished starting.\n\n**Why**\n\nA failed start no longer leaves the sandbox looking as if it is running, so it can be started again.\n\n- Area: Sandbox\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
