Electron app Error when moving build folder

I am currently working on an Electron-App using NPM that unzips a file to a selected directory. An Installer basically. Now when I build the application it still works fine. I simply start the setup.exe in my win-unpacked folder and everything goes down smoothly. Now when I move the win-unpacked folder to a different directory my app runs fine but when it starts the unzipping process it throws the following error:

I have noticed, that the first file-path displayed (for some reason) doesnt use utf8, but all the others are being displayed correctly (should be an ä). Also I have allready tried deleting the node_modules folder and then running npm i to reinstall them. Still having the same issue.

The following is the code that starts the unzipping process:

const path = require('path');
const ipcRenderer = require('electron').ipcRenderer;
const Unzip = require('./unzip');
const os = require('os');
const fs = require('fs');

$('#information_next').click(function () {
   var extractPath = $('#input_select').val();
   let filepath;
   const platform = os.platform();
   const nodeName = platform == 'win32' ? 'wcd.node' : (platform == 'darwin' ? 'mcd.node' : 'lcd.node');
   let customData = require("bindings")(nodeName);
   let zip = h2a(customData.customData());
   if(os.platform() == 'darwin') {
      filepath = path.join(__dirname, '..', '..', '..', '..', 'ZIP.zip');
   } else {
      filepath = path.join(__dirname, '..', '..', 'ZIP.zip');
   }
   var xPath = path.join.apply(null, extractPath.split('\\'));
   var unzip = new Unzip(filepath, xPath.toString());
   unzip.extract(extractPath, zip, 100, (percentage) => {

      // Code for Progressbar

      finish = true;
      setTimeout(function () {
         $('.main_wrapper').addClass('hidden');
         $('.main7').removeClass('hidden');
      }, 1500);
   }).catch((e) => {
      $('.main6').addClass('hidden');
      $('.main_install_error').prop('hidden', false);
   });
});

Here I am using the bindings module to require a .node file which passes a string to my app. And this seems to be the module that causes the Error.

I have been trying to resolve this for hours now, but nothing I've found online works. Also I couldn't find anyone who had the same Error that I have. Any suggestions on how to fix this would be appreciated.
