Hey @Tristen35406518vrvd 
Quick question, do you see the same error when trying to open a backup catalog, or is it only happening with one specific catalog file?
Thanks so much!
Alek

    Hi @Tristen35406518vrvd,


    Thank you for confirming that this issue occurs with all catalogs; that’s really useful context. Since Lightroom Classic isn’t opening any catalog and is also blocking uninstallation, it sounds like a hung background process or corrupted configuration files might be preventing Lightroom from launching properly. Let’s try a few cleanup and reset steps:
     • Ensure Lightroom Classic and Creative Cloud Desktop are fully closed (check Task Manager > Details tab for any lingering Lightroom or CC processes and end them if present).
     • Reset preferences manually. (https://adobe.ly/47Rl97J)
     • Then relaunch Lightroom Classic to see if it opens correctly.
     • If the app still fails to open, try reinstalling Lightroom Classic after running the Adobe Creative Cloud Cleaner Tool to remove any damaged components.

     

    If it does open afterward, try creating a new blank catalog and then use File > Import from Another Catalog to recover your work from backups or existing catalogs.


    Additionally, could you confirm whether any third-party antivirus software, drive syncing tools (such as OneDrive), or backup utilities are actively scanning your catalog folder?


    Let me know how it goes, Tristen. Once we confirm whether Lightroom launches after resetting preferences, we can escalate the issue further to the product team if it still refuses to open any catalog.


    Best,

    Anshul Saini
