Lightroom classic denoise feature not working on RAW files

Hey @georgiaa43347191, 

I wanted to check in and see if any of the shared suggestions have helped you resolve the issue. If not, could you share more details? @AxelMatt asked exactly what I was going to ask. 🙂 

Best,

In addition to the other suggestions, type "i" in Develop to see the file name and verify it is in fact a raw file rather than a non-raw (JPEG, TIFF, etc.).  There are many reports here of people convinced they're editing a raw when in fact they're not -- the default settings in LR hide that from you.

See if the answer marked as correct in this thread solves it: https://community.adobe.com/t5/lightroom-classic-discussions/denoise-stopped-working/td-p/14092087

Please give us more informations.

Which RAW format from which camera type dp you use?

Which version of Lightroom Classic do you use?

What happened on ypou system before the error occured (software update, patch installation etc.)?

Please provide also a copy of your 'System Info'. This can be get from the LrC Help > System Info menu item. There's a copy button in the System Info dialog. Press this button and paste the info into your next forum post.

In the meantime you can 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 to the default settings:
