JavaScript Node Segmentation fault

Question

I'm currently working on a Windows 11 Laptop and Ubuntu 22LTS desktop PC. Only on PC the program suddenly interrupts. After some research I found out it's running in an 'Segmentation fault' - error, when loading some data from a postgres DB and creating an Object with it. The error occurs as soon as the constructor is called.

import SegFaultHandler from 'segfault-handler'

SegFaultHandler.registerHandler("crash.log")

export async function _init(containerName) {
    let sqlQueries = {
        loadItemData: {
            syntax: 'select * from containercontent where itemname = $1',
            variables: [containerName],
        },
    };
    let containerData = await dbHandler
        .sqlQuery(sqlQueries.loadItemData.syntax, sqlQueries.loadItemData.variables)
        .then((res) => res.rows[0]);
    let Container = new Container();

    return Container;
}
export class Container extends MarketObject {
    constructor() {...} // <-- the error occurs

I have already reinstalled vsCode, node, npm and all dependencies. I also googled and followed some instructions. One of them was to install the 'segfault-handler'. Now I have a log, but I don't understand it:

Waiting for the debugger to disconnect...

Is anybody able to read some meaningful hint out of it?

New Info:

Seems like the following function after the constructor is causing the error:

export class Container extends MarketObject {
    constructor() {...} // <-- the error occurs
    
    saveDBData = async function () { //<--this function causes the error
        await dbHandler.sqlQuery(this.sqlQueries.saveItemData.syntax, 
           this.sqlQueries.saveItemData.variables);
     }
...
};

Just for your notice, the dbHandler.js looks like this, but I realy don't think its faulty. I'm using this all over the program:

import pg from 'pg';
import ini from 'ini';
import fs from 'fs';
import { error } from 'console';

async function getConnection() {
    try {
        let dbaccess = ini.parse(fs.readFileSync('./tools/database/db.ini', 'utf-8'));
        let client = new pg.Client(dbaccess['postgresql_loginData']);
        return client;
    } catch (error) {
        console.error(error);
        console.error(error.message);
    }
}

export async function sqlQuery(syntax, values) {
    try {
        let client = await getConnection();
        await client.connect();
        let res = await client.query(syntax, values);

        await client.end();

        return res;
    } catch (error) {
        console.error(error.stack);
    }
}
