Lightroom Classic doesn't open

Some people have reported that if just let Lightroom Classic run for hours, it does open and then after that launching the program takes a reasonable/normal amount of time.

PLEASE DO NOT TYPE IN ALL CAPITAL LETTERS.

You need to give more information (and posted in the wrong forum). We need to know your computer hardware specs, the OS (Mac or Windows), the version of the OS and the version of Lightroom Classic. We also need to know what exactly happens when you try to launch Lightroom Classic.
