Module directory modules/queues.tf does not exist or cannot be read
A Terraform module is represented by a whole directory, not an individual file. If you create a directory ./modules/queues and move ./modules/queues.tf to ./modules/queues/queues.tf then you can call that module like this:

module "pae_queues" {
  source = "./modules/queues"

  environments = var.environments
}
