Ubuntu 18.04.4 Bionic does not run any newly installed application

I am trying to install Opera browser or Chrome or any other available application on Linux.
The installation is clean and no error is thrown. However upon clicking on the application the cursor shows spinning around and after a few seconds nothing happens.

Welcome to Ubuntu 18.04.4 LTS (GNU/Linux 4.15.0 x86_64) is written at the top of my command prompt.

sed -i -e 's@Exec=/usr/bin/google-chrome-stable %U@Exec=/usr/bin/google-chrome-stable %U --no-sandbox@g' /usr/share/applications/google-chrome.desktop
