Libre Office 6.2.2 won't open in Windows 10

Nothing happens when Libre Office 6.2.2 icon on desktop is clicked on Can I delete Libre Office 6.2.2, reinstall LO 6.2.2 without losing document files?

Could you please explain why you are duplicating a question needlessly? This is third time with same basic question. Original here → LibreOffice 6.2.2 Start Issue on Windows 10 and answered here also → Version 6.2.2 keeps crashing If I delete this version and reinstall… will I lose all of my saved documents?
