}

//Create a resource group and nsg

resource "azurerm_resource_group" "Customer" {
  count = length(local.group_names)
  name  = local.group_names[count.index].resource_group_name
  location = local.group_names[count.index].region
} 


//Create a Vnet
resource "azurerm_virtual_network" "Customer" {
  count               = length(local.group_names)
  name                = local.group_names[count.index].virtual_network_name

  resource_group_name = azurerm_resource_group.Customer.name
  address_space       = [local.group_names[count.index].address_space] 
}

As the error show, you could change the code like this

resource "azurerm_virtual_network" "Customer" {
  count               = length(local.group_names)
  name                = local.group_names[count.index].virtual_network_name
  location            = azurerm_resource_group.Customer[count.index].location # add [count.index]
  resource_group_name = azurerm_resource_group.Customer[count.index].name  # add [count.index]
  address_space       = [local.group_names[count.index].address_space] 
}
