Question

Lightroom Classic won't open after Windows 11 repair update

I was using Lightroom v15.2 on my laptop (ASUS ProArt H7604JV, i9-13980HX, 32GB RAM,  RTX4060, Win 11 Home 25H2) when I discovered that the Thunderbolt drivers were no longer installed so I couldn’t connect my second monitor. I attempted to use Windows Update to repair Windows and after the “repair” Lightroom wouldn’t open. With the task manager open I can see that Lightroom opens in background processes but never actually starts. I’ve tried uninstalling and reinstalling and still nothing. I’ve tried opening backed-up catalogs and nothing. I’m going crazy trying to open lightroom so any help is appreciated!

    In a first step you should  try to reset the Lightroom preferences.

    It's recommended to backup your preferences before you reset the preferences to the default settings:
