Port 22 is added to the worker node security group in TF install [1]:

resource "aws_security_group_rule" "worker_ingress_ssh" {
  type          	= "ingress"
  security_group_id = aws_security_group.worker.id
  description   	= local.description

  protocol	= "tcp"
  cidr_blocks = var.cidr_blocks
  from_port   = 22
  to_port 	= 22
}

But it's missing in SDK install [2]
