Also, FWIW, here is the configuration for my single node cluster which works - note the io_engine.

mayastor: {
  obs: { callhome: { enabled: false } },
  'loki-stack': { enabled: false },
  etcd: { replicaCount: 1 },
  nats: { cluster: { enabled: false } },
  // https://www.talos.dev/v1.8/kubernetes-guides/configuration/storage/#deploy-mayastor
  csi: { node: { initContainers: { enabled: false } } },
  // Without this, io-engine crashes
  io_engine: { envcontext: 'iova-mode=va' },
},
