The Microsoft-Certificate Management subflow contains a PowerShell step. When Flow Designer attempts to load the subflow, it cannot resolve the step definition because the required plugin is not installed or is deactivated. This causes the step provider to throw a "Step definition not found" error, which surfaces as the subflow-not-found popup.
