As @jitter answered, if using kind = BlobStorage, the accessTier in properties is required. reference

resource storageAccount1 'Microsoft.Storage/storageAccounts@2023-05-01' = {
  name: 'satest111'
  location: 'westus'
  sku: {
    name: 'Standard_LRS'
  }
  kind: 'BlobStorage'
  properties: {
    accessTier: 'Cold'
  }
}

Try to use kind = 'StorageV2' to make it easy if the kind not mandatory, v2 type is also recommanded.

resource storageAccount2 'Microsoft.Storage/storageAccounts@2023-05-01' = {
  name: 'satest222'
  location: 'westus'
  sku: {
    name: 'Standard_LRS'
  }
  kind: 'StorageV2'
}

here is a sample reference
