VERY interesting, it means that for some mysterious reason it's not allowing you to use an updated javascript interpreter... hmm...

No worries, I'm very sorry you're experiencing such troubles over this. If you're willing to keep going, I'd love to work with you to solve it~ game dev can be a headache, but generally it never involves this level of debugging. But hey =D once we solve it, you'll be able to solve this issue for other developers who might run into the rare problem as well!

Replace the js code I sent with this, for 'editor.js'

const { app, BrowserWindow } = require('electron');
function createWindow() {
  mainWindow = new BrowserWindow({
    width: 816,
    height: 624,
    frame: true,
    webSecurity: false,
    webPreferences: {
      nodeIntegration: true,
      contextIsolation: false,
      webSecurity: false,
    },
  });
  mainWindow.loadFile(require('path').resolve('./', 'index.html'));
  mainWindow.webContents.openDevTools();
}
app.whenReady().then(createWindow);
app.on('window-all-closed', () => {
  if (process.platform !== 'darwin') {
    app.quit();
  }
});
app.on('activate', () => {
  if (BrowserWindow.getAllWindows().length === 0) {
    createWindow();
  }
});

then run electron ./editor.js from the powershell~ remember to hold left shift, right click an empty space in your RPG Maker's project directory first and select "Open powershell here"

EDIT:

Also, I really don't mind, feel free to vent lol, don't hold back I 100% get it. sometimes I wanna scream and rip my hair out (whenever it grows back from the previous ripout!)

Yeah it seems RPG Maker isn't treating you well at all... I'm so sorry it's doing that to you. VERY strange also for electron to not allow you to use modern JS... something unknown is going on from a deeper level, I'm willing to work with you to try and get it figured out but maybe we should Discord from here, as we might need to do some *cracks knuckles* anti-jank special methods I've developed from dealing with my own "this makes no f*ing sense" problems xD
Though imo, you might be better using Godot
