.env Settings ignored in session driver

Just a comment - I have had "strange" problems with env lately - https://github.com/codeigniter4/CodeIgni...ssues/3992
I have stopped relying on the magic .env for many things and replaced with standard php getenv() in this way:

$this->default['password'] = getenv('CONFIG_RDS_PASSWORD', true);

I still set CONFIG_RDS_PASSWORD in my .env.
