Adobe Lightroom classic will not open on my laptop

On a first step try to reset the preferences of Lightroom Classic:  How to reset Lightroom Classic preferences (adobe.com)

It's recommended to backup your preferences before you reset the preferences:  https://helpx.adobe.com/lightroom-classic/kb/preference-file-and-other-file-locations.html

If this doesn’t help the next step is to switch off the GPU support from the Lightroom preferences and check if that helps to fix the issue. If Lightroom doesn't start correctly the please see "Solution 2" in the document behind the link below.

Troubleshoot GPU issues | Lightroom Classic (adobe.com)

If it's help see here Troubleshoot GPU issues | Lightroom Classic (adobe.com) and check the different steps.

If this also doesn’t perhaps a issue with your catalog. Restore the catalog from a recent backup -> Disaster strikes - a corrupted catalog! | The Lightroom Queen

or create a new catalog .

Hold the Ctrl-Key while starting LrC. This opens a catalog selection dialog.

Click on “Create a New Catalog” to create a new one and see if this catalog works. If yes, you could then try to import your current catalog into the new one.

Hi, thanks for reaching out! We're sorry about the trouble.

Please let us know the version of Lightroom Classic you're using, along with your computer's operating system. Have you tried reinstalling the application to see if that makes a difference? If not, please try that and let us know how it goes.

Thanks,
