Translation to English

I'm currently using the latest version of Lightroom Classic and it inexplicably stopped working. It was used a couple of days ago without problems. Does anyone know what it can be?, it remains in processes as working but nothing is shown on the screen.

Please describe "inexplicably stopped working" in detail. Exactly what does happen?

Hello and thanks for the reply. I can not open Lightroom Classic app from Creative Cloud pannel or even from the current access from my desktop. It stop working without showing any error. The status from Cloud pannel says it´s working but nothing appears. Only showing activity like a process. I tried to uninstall and install but nothing changes.

Please check if there's a .lock file next to the LR catalog in the appropriate folder.

If there's such a .lock file it 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 you can try to reset the LR preferences to the default settings.

How to reset Lightroom Classic preferences (adobe.com)

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

The next is to try the following steps:

• Close Lightroom
• Backup the folder : C:\Users\<username>\AppData\Roaming\Adobe\Lightroom to a save location and then rename it to LightroomOld
• Restart Lightroom

Note: Normally the AppData subfolder is hidden. How to show this folder see here:

How to Find and Use the AppData Folder in Windows 

Another try is to hold the Ctrl-Key while starting LrC. This opens a catalog selection dialog.

Select the appropriate catalog and let check it – note the checkmark to check its integrity. If that does not help, try to create a new one and see if this catalog then works. You could then try to import your current catalog into the new one.

If this already doesn't help, provide a copy of your 'System Info'. This can be get from the LrC Help > System Info menu item. There's a copy button in the System Info dialog. Press this button and paste the info into your next forum post.

What has been changesd on your system before the issue occur?

Thanks everyone for your kind help, after installing an older version (13) while starting it showed a catalog conflict which did not happen at versión 14. After fixing this catalog issue the problem was solved. I don´t know why this error was not showed in the last update. Thanks!
