QGIS software missing on laptop after trying to update to latest version

I am facing an issue with QGIS installation. I tried to upgrade my QGIS to version QGIS 3.14, I couldn’t locate it on my laptop anymore. However, I can see it in the uninstall section of my laptop. I have tried uninstalling it and re-installing it back, yet, I am still faced with same problem.

Following the file path I created during the installation, I found the QGIS 3.14 folder on my ‘program files’, but didn’t find a shortcut icon. I saw and run the qgiscrashhandler.exe, but a System error pop-up tells me that Qt5Widgets.dll, Qt5Gui.dll, Qt5Core.dll were not found. Reinstalling the program may fix this problem. I have reinstalled and redownloaded QGIS software countless times, yet the issue subsists.

How can I resolve the issue?
