These modules work fine with the 1.18 Google provider. At that version the google-beta provider did not exist. Here you have a working example.

provider "google" {
  region = "europe-west1"
  version = "1.18"
  project = "yourproject"
}


module "nat" {
  source     = "GoogleCloudPlatform/nat-gateway/google"
  version    = "1.2.2"
  region     = "europe-west1"
  network    = "default"
  subnetwork = "default"

}

module "mig" {
  source            = "GoogleCloudPlatform/managed-instance-group/google"
  version           = "1.1.15"
  region            = "europe-west1"
