Start by reproducing the failure while Claude checks VM sandbox status on Windows with Claude Code 1.49585.0, then inspect the reported SDK path and .verified marker under the Claude workspace. Confirm whether reinstalling or restarting changes the result. Done means the workspace starts reliably without the RPC verification error.
