Credentials not load from DB

[Memurame]

Good day
I have the Settings extension in use.
As far as I understood the extension should load the data directly from the DB.
Unfortunately this does not work.
I have saved the connection data from the e-mail in the DB and now I want that they are automatically loaded when I want to send a mail.

MyCodeigniter version

"php": "^7.4 || ^8.0",
"codeigniter4/framework": "^4.3.2",
"codeigniter4/settings": "^2.1"

In my test controller I have inserted a simple mail dispatch which works otherwise perfectly if I insert the access data directly into the .env.
I put these parameters in the .env file and it works.

email.protocol = 'smtp'
email.SMTPHost = 'galvani.metanet.ch'
email.SMTPUser = 'no-reply@domain.ch'
email.SMTPPass = 'oS7XV8L'
email.SMTPPort = '465'
email.SMTPCrypto = 'ssl'
email.mailType = 'html'
email.fromEmail = 'no-reply@domain.ch'
email.fromName = 'Test Name'

$email = \Config\Services::email();
$email->setTo('mail@mail.ch');
$email->setFrom('abs@mail.ch');
$email->setSubject("Überfällige Rechnung");
$email->setMessage("Test");
if ($email->send())
{
    echo 'Email successfully sent';
}
else
{
    $data = $email->printDebugger();
    print_r($data);
}

When testing, I get the following error message:

You did not specify a SMTP hostname.

And how did you resolve your issue?

That was a long time ago.
Unfortunately, I can't tell you anymore.

I think I made a mistake.
Sorry.
