P: Photoshop 27.10: "Edit in Photoshop" from Lightroom Classic & Lightroom Desktop does not load image with Denoise

Since today’s Photoshop 27.10 update, the “Edit in Photoshop” command in Lightroom Classic 15.5.1 is not working anymore for me. Photoshop opens automatically as before (if it’s not open yet) but no image is being loaded. Downgrading Photoshop to 27.9.1 resolves the issue and the “Edit in Photoshop” functionality is back to normal. I also tried to change the external editing file format from TIFF to PSD or PSB but this didn’t make any difference. Anyone else facing the same issue? 

I’m running macOS Tahoe 26.6.2. Closing and re-opening LRC and PS didn’t solve the problem, rebooting the machine also didn’t show any effect. 

P.S.: I posted this in the Photoshop forum as well

      Hi everyone,

      Thank you for the detailed reports and reproductions here. It has been really helpful in isolating the issue quickly. I’ve filed this for the engineering teamto investigate and prioritize. 

      In the meantime, here are confirmed workarounds:

      • Downgrade to Photoshop 27.9.1 via the Creative Cloud app (Other versions > 27.9.1).
      • Alternatively: Temporarily disable Denoise in Lightroom Classic before sending to Photoshop, then re-apply back in Lightroom, or it using Camera Raw as a filter inside Photoshop.

      We understand this disrupts a core editing workflow and appreciate your patience. We'll update this thread as we have more information.

      I have uninstalled and reinstalled both programs. I have rebooted, I have, checked to make sure they have access. I have re-entered the external editing portion in preferences. Nothing is working. This has caused so much delay in my work delivery.

      I have the most current versions of Lightroom Classic and Photoshop. When I select ‘edit in Photoshop 2026’ Photoshop launches but the image doesn’t open in Photoshop.

      There appears to be a reproducible compatibility issue between Lightroom Classic’s AI Denoise and the “Merge to Panorama in Photoshop” workflow.

      When I send images from Lightroom Classic to Photoshop as a panorama, the Photomerge dialog opens normally and allows me to select the panorama method. However, after confirming the settings, Photoshop does not process or assemble the panorama.

      I was able to isolate the problem to Lightroom Classic’s Denoise setting.

      Reproduction steps:

      1. Import RAW images into Lightroom Classic.
      2. Apply Lightroom Classic’s AI Denoise to the images.
      3. Select two or three images.
      4. Choose Photo → Edit In → Merge to Panorama in Photoshop.
      5. The Photomerge dialog opens normally.
      6. Select a panorama method (e.g. Auto) and confirm.
      7. Photoshop does not assemble the panorama.

      Important findings:

      • With Denoise disabled, the same panorama workflow works correctly.
      • The problem also occurs with only one image having Denoise enabled and the other image(s) having Denoise disabled.
      • The problem occurs with only two images, so it is not related to the number of images.
      • If I reset the Lightroom development settings, the panorama works.
      • If I enable Denoise again, the panorama fails.
      • Opening the same images directly in Photoshop and using File → Automate → Photomerge works correctly.
      • Sending the Lightroom-developed image from Lightroom Classic to Photoshop as a Smart Object also works correctly.

      Therefore, the issue appears to be specifically related to the Lightroom Classic → Photoshop “Merge to Panorama” workflow when at least one source image has Lightroom AI Denoise applied.

      This is fully reproducible with the same images by simply enabling or disabling Denoise.

      Expected behavior:

      Photoshop should receive the Lightroom-developed images and complete the Photomerge operation normally, including when Lightroom AI Denoise has been applied.

      Actual behavior:

      The Photomerge dialog opens, but after confirming the settings, the panorama is not assembled and the process does not complete.

       

      System information:

      • Lightroom Classic version: 15.5.1
      • Photoshop version: 27.10.0
      • Camera Raw version: 18.5.1
      • Operating system: [WINDOWS 11 Pro 25H2
      • GPU: NVIDIA GeForce RTX 2070 (8 GB)

      Please investigate the interaction between Lightroom Classic AI Denoise and the “Merge to Panorama in Photoshop” workflow.

      Camera Data - Nikon D850 - 44MM Raw File

      Photoshop Version - Adobe Photoshop Version: 27.10.0 20260824.r.26 9d9635d  arm64 (final, Release)

      Lightroom Version - Lightroom Classic version: 15.5.1 [ 202608131348-cab7eed5 ]

       

      Open an unedited NEF file in Lightroom. Click “Edit in Photoshop”. Photoshop launches and the image opens as a layer in Photoshop.

      Open a basic edited NEF file in Lightroom. Click “Edit in Photoshop”. Photoshop launches and the image opens as a layer in Photoshop.

      Open a Denoise edited NEF file in Lightroom. Click “Edit in Photoshop”. Photoshop launches but the image DOES NOT open as a layer in Photoshop.  All you get is the Welcome to Photoshop screen.

      Twice, I uninstalled Photoshop, then Lightroom. Then restarted my computer (Mac Mini). Then installed Photoshop and Lightroom (in that order).  The problem still persists.

      Are you using a Mac on Tahoe OS?
      If so, there is a bug in Photoshop 27.10 that causes this.
      Until it gets fixed, downgrade to version 27.9.1.
