can't connect any more "Error encountered when loading your Zowe config."

[GitMensch]

Describe the bug
Four months ago, everything worked like a charm...
Several updates to the OS and vscode later, the profiles cannot be loaded any more:

Error encountered when loading your Zowe config. Click "Show Config" for more details.

(and then I see the unchanged config with no error shown):

{
    "$schema": "./zowe.schema.json",
    "profiles": {
        "LearnCOBOL": {
            "properties": {
                "host": "example.company-name.net"
            },
            "profiles": {
                "zosmf": {
                    "type": "zosmf",
                    "properties": {
                        "port": 10443
                    }
                }
            },
            "secure": [
                "user",
                "password"
            ]
        },
        "base": {
            "type": "base",
            "properties": {
                "rejectUnauthorized": false
            },
            "secure": []
        }
    },
    "defaults": {
        "zosmf": "LearnCOBOL.zosmf",
        "base": "base"
    },
    "plugins": []
}

SSH login outside of vscode (or in its terminal) still works,

Expected behavior

Zowe config loading works, or clear messages what the error is.

Desktop (please complete the following information):

• OS: Debian GNU/Linux trixie/sid (command-line only, connected to using OpenSSH extension, as done 4 months ago, everything else works in vscode on that machine)
• Zowe Explorer Version: 3.1.2, 3.0.3, 2.18.1, 2.18.0

Additional context

When downgrading to 2.18.0 I've seen a different error message:

Error: Failed to load Keytar module: libsecret-1.so.0: cannot open shared object file: No such file or directory ProfInfoErr: Failed to initialize secure credential manager

Manually installing that, I got a different message on window reload:

Error: [keyring] "glib" library returned an error:

""The name org.freedesktop.secrets was not provided by any .service files"" ProfInfoErr: Failed to initialize secure credential manager

After then upgrading to 2.18.1 I get

Error: Failed to load Keytar module: Cannot find module '@zowe/secrets-for-zowe-sdk' ProfInfoErr: Failed to initialize secure credential manager

(installing that module via npm install did nit help, neither with nor without -g option, so I've removed both after the test)

After upgrading to newest version again I get:

Failed to initialize secure credential manager

with a hint to the log that contains the same message

@JTonda why is that a discussion (and labeled as bug), not an issue?
