Electron crashing when opening more than one application

I'm going through a little problem: c

Whenever I open more than one Electron application and it starts loading a new main window for the user to start using the application, the entire operating system gets extremely slow for a few seconds until the page is fully loaded. >

This happens only when you open more than one Electron application. In my case, I'm using Windows 10.

Question update

Mysteriously other applications that run Electron such as Discord, do not make that problem happen.

This happens only between my applications developed on Electron.
