AI Denoise is Not Working with my M1 Ultra Mac Studio, Regardless of File Type

I am currrently using an M1 Ultra Mac Studio with Lightroom version 8.5 and macOS Sequoia 15.6.

I am unable to get AI Denoise to work with any file type (DNG, NEF, RAW, etc.).

I've tried uninstalling/reinstalling Lightroom. Made sure I was using the latest version. Checked to make sure all the file types I was using were supported, but the problem still persists.

When I try to click on the "Denoise" box, it brings the screen up with the progress bar, and looks like it's running without issue. But after about 2-3 second of running, it just cuts out and does not progress any further (progress bar/box disapears and goes right back to the normal edit screen). Then when I try to click the "Denoise" box again, it won't even bring up the progress bar screen.

Other AI/generative functions are working without issue. It's just the Denoise.

Any guidance/help troubleshooting/resolving the problem would be greatly appreciated.

Thank you.

Were you able to resolve the issue...I got the same problem with 8.5.1 Lightroom on my Macbook M1 Pro.

@Sameer K - That worked! Thanks so much.
I do have a question - If I do want to use Photoshop, will this affect the cross app functionality?

Thanks for confirming this. You can launch Photoshop & use Adobe Camera Raw to Denoise, and it should work. If it doesn't work, you'll just need to reinstall Photoshop via the Creative Cloud desktop app, and it should continue to function as expected.

Thanks!

Hey, @helpful_genius0046. Welcome to the Lightroom Community. I'll need more information to help you figure this out. Please share the system information from Lightroom under Help > System info > Copy and paste into a text document > Upload and attach here.

Are any of the images synced from Lightroom Classic? In Lightroom, open any image & check the 'i' Info panel to find the current sync status.

Let me know how it goes. Thanks!
