So this post is a little off track but I really wanted to share this because it is such an issue and has been for a long time now and LibreOffice doesn’t seem to be in any hurry to fix it. Listen, I love LibreOffice but only if it works. From what I have seen while looking around the web this issue has been a problem since about 2015.
LibreOffice fails to load. You will click on the icon, or start from terminal and you get a splash screen and then nothing.
(Based on our Parrot Security Debian OS)
Uninstall LibreOffice and install OpenOffice by Apache.
Now if you look into your Office menu folder you will see all your OpenOffice icons ready to use.
