Local catalog Problem

Question

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:On Windows Close LightroomHold down the [windows key] and Press [ R ] to bring up the run dialogType %appdata% and hit returnNavigate  the file path through Local to Data and open the folder with a long string of numbersRename the file {Managed Catalog.mcat} to {Managed Catalog.old}Delete the {previews.db } databaseClose Explorer and re-launch LightroomWait for sync to complete
