Lightroom Classic Will Not Launch

I have Lightroom Classic, Photoshop, and Lightroom (Not Classic). I cannot get LrC to open on my computer. I've tried uninstalling and reinstalling, I've tried to clear out my preferences when uninstalling, and I've tried Alt + Shifting while clicking on LrC to officially clear out my preferences. I can get it to work on my mother's computer, but I can't get it to work on mine. Please help. I need LrC for both school and for business opportunities. Both Lr regular and PS work correctly, but LrC does not. I don't know what else to do to get it to work.
