Lightroom doesn't launch on computer

[Perrine5D95]

Bonjour, 

J'ai depuis plusieurs mois un soucis d'ouverture quand je lance Adobe Lightroom, l'image de démarrage du programme s'affiche et puis plus rien. La mention Lightroom apparaît en haut da la bordure de mon mac mais rien d'autre.

Hi there,

Sorry that Lightroom on your computer does not launch and freezes.

Would you mind sharing the exact version of the Lightroom app you're using along with your computer's OS?

Would you mind restoring Lightroom app preferences to default and let us know if the issue still persists? Please refer this article for step by step instructions:
