Local catalog Problem

[giuliano_5985]

Hi everyone,
I haven't been able to access Lightroom for two days. When I open the application, a message appears about an undefined problem with the "local catalog" and the two options I'm given are to restart the program or exit the app; in both cases, the problem recurs. However, I have no problems using the web browser or smartphone versions. Has anyone encountered similar issues and could help me?

Additional information:
- Windows 11 OS
- Lightroom desktop

Thank you so much!

Try this suggested fix-

As Lightroom's catalog is in the cloud, you can delete the local catalog (or just rename it) and restarting LR will make it recreate one.  WIth the cloud-dependent Lightroom (Lightroom-Desktop), think of its catalog as just being a cache for when you are working offline.

To re-build the local catalog in Windows:

1. On Windows Close Lightroom
2. Hold down the [windows key] and Press [ R ] to bring up the run dialog
3. Type %appdata% and hit return
4. Navigate  the file path through Local to Data and open the folder with a long string of numbers
5. Rename the file {Managed Catalog.mcat} to {Managed Catalog.old}
6. Delete the {previews.db } database
7. Close Explorer and re-launch Lightroom
8. Wait for sync to complete
