For future references, please refer thread where the issue is discussed.
What worked for me is running the following command: sudo sysctl kernel.unprivileged_userns_clone=1 you will need to do it every time you restart your computer.
For avoid doing it every time you restart the computer you may added it to your sysctl.conf file by doing the follow: in the terminal sudo nano /etc/sysctl.conf and in any empty line just add kernel.unprivileged_userns_clone=1 then Ctrl + O > Enter > Ctrl + X and you will have save the file.
As per other people said, there are some security concerns which they couldn’t exactly determine how or why. It seems like the majority of OS have the feature disable without any trouble, but for some reason Debian enable it and it creates a conflict with Electron.
Thanks everyone.
