When checking the "Denoise" checkbox in Lightroom Classic 15.4, an error occurs:

This occurs for a raw file from the Sony ILCE-7RM4 as well as for a raw file from the Leica Q3.

Lightroom Classic 15.4

macOS Tahoe 26.5.1

Apple Mac Studio 2022 (M1)

Here is a screenshot of the Performance of the Lightroom Classic Preferences:

    Thank you for the two sample files. 
     

    I downloaded both of them and imported them into an LrC 15.4 catalog. I’ve attempted Denoise on both files, and they both complete successfully.  I can also select both and run Denoise in batch, and both complete successfully.

    I am unable to reproduce your issue. 

    I am testing using a Mac M4 running Tahoe 26.5.1

      That's sad. Most likely my problem is caused by the older hardware of an M1 Mac Studio?

      It puts us firmly in the check out your system, unfortunately. 

      This procedure works for both Lightroom Classic and Lightroom Desktop.

      If you are using Lightroom Desktop, it can change your local storage location. Please review this setting after resetting preferences. 

      Reset Procedure:

      1. Close Lightroom.

      2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom.

      3. Overwrite the Preferences when prompted by the dialog.

      4. Close Lightroom.

      5. Restart Lightroom.

       

      If that doesn’t work:

      Clean Lightroom Install Procedure

      Close Lightroom

      Restart the computer

      Use the Adobe Creative Cloud App to uninstall Lightroom

      Restart the computer

      Install Lightroom via the Creative Cloud App without launching any other programs.

      Restart the computer

      Launch Lightroom

      Wait 5 minutes

      If that fails to correct the issue, the next test is to attempt the same using a different OS User ID to see if it works. A corrupt OS User Profile would be revealed by this test.

        Greetings,

        I saw your post on Victoria’s blog. Thank you for reaching out to us here. 


        Is it possible to share one file from both of your cameras that exhibit the issue.  Please upload to a sharing service and DM me the link. 

         

        Thanks!
