Issue while propagating Launch Template changes to AWS by Terraform - No changes detected by Terraform

Question

I made changes to lifecycle block from true to false for create_before_destroy parameter in below code and did a terraform plan. It did not detect a change. Am I doing something wrong ? Shouldn't it create a new launch template version ?

resource "aws_launch_template" "yct_asg_temp" {
  name          = "yct-lt-${var.env_id}-${random_string.random.result}"
  image_id      = data.aws_ami.control_tower.id
  instance_type = var.instance_type
  ebs_optimized = true
  key_name      = var.ec2_key_name

  update_default_version = true

  iam_instance_profile {
    arn = aws_iam_instance_profile.ssm_instance_profile.arn
  }

  network_interfaces {
    security_groups = [aws_security_group.yct_sg.id]
    subnet_id       = module.vpc.public_subnets[0]
  }
  
   lifecycle {
    create_before_destroy = false
  }

  block_device_mappings {
    device_name = "/dev/sda1"
    ebs {
      volume_type           = "gp3"
      volume_size           = var.ebs_root_volume_size
      encrypted             = true
      delete_on_termination = true
    }
  }

  user_data       = base64encode(local.user_data)
  
  tag_specifications {
    resource_type = "instance"
    tags          = merge({ Group = "ec2-instance" }, var.tags)
  }

  tag_specifications {
    resource_type = "volume"
    tags          = var.tags
  }
}
