LIGHTROOM CLASIC

No puedo abrir la aplicación lightroom

A lot more information is needed. Please provide the following basic information:

If Lightroom is running it creates a .lock file for the opened catalog next to the approriate .lrcat file. 

On LRs regulary shut down this file was deleted. If LR crashes the .lock file remains in the appropriate folder. 

In this case the .lock file must be deleted manually. 

More informations about this, you'll find here:  

The Lightroom catalog cannot be opened because another application already has it opened - lrcat.loc... 

If this doesn't help please try is to switch off the GPU support from the Lightroom preferences and check if that helps to fix the issue. 

Go to Lightroom > Preferences > Performance tab > Uncheck "Use Graphics Processor" > Restart Lightroom.

Another step is to try to reset the Lightroom preferences.

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