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.

      Try unchecking “Denoise” in the Details tab of Lightroom for the files that aren’t exporting to Photoshop for you. In my case, as soon as Denoise is checked, the files won’t be sent to Photoshop and when I uncheck the box, they export fine.

        No solution from me, just want to ask if you watched/checked Activity Monitor. On my system, LrC 15.5.1 is using 6.8GB of my 8GB MacAir RAM. Ps 27.10.0 is using 4.2GB. The 11GB is Unified, I assume.

        But my image did open during LrC->Ps. Exiting without making edits is prompting “Save changes...before closing?” which is new.

        For me, the “Edit in Photoshop” command in Lightroom is not working anymore. Photoshop opens fine but no image is being loaded. This is a feature I use on a daily basis and the only way to resolve it for me was to downgrade Photoshop to 27.9.1. Seeing that people have a lot of other issues, I think it makes sense to stay on 27.9.1 for now and not upgrade before all the bugs are hopefully resolved in the next version.

          What often works in a situation like this is uninstalling both Lightroom Classic and Photoshop (keep the preferences so this will go smooth and easy) and then first installing Photoshop and then Lightroom Classic. The order is important!

          Thanks for your suggestion, JohanElzenga. What’s the preferred way to do this? I not only want to keep all my preferences but also my plugins, panels, actions, etc. that are installed for both Lightroom and Photoshop. Is there an easy way to keep all these and still uninstall / reinstall both apps without losing anything?

          ​@JustCallMeDrew If you directly reinstall PS and LrC the settings are retained.

          If you first uninstall the application you would be ask if you like to keep the preferences.

          When the 'link' between Lightroom Classic and Photoshop has issues, is to try this:

          Use the Adobe Creative Cloud Application to uninstall Photoshop. When asked, keep preferences! After this reinstall Photoshop again.

           

          If this doesn't help the next step is a reinstallation of both apps Lightroom and Photoshop. Please follow the steps below:

          1. Open the Adobe Creative Cloud Desktop Client and uninstall both Photoshop and Lightroom Classic. When asked, keep preferences! 
          2. Install Photoshop first and then Lightroom Classic. The right order is very important here!

           

          If this doesn't help try the reinstallation with removing the preferences also.

          Well, this is not only about “link” between LRC and PS. 

          When LRC is running, PS cannot start from Windows, not by invoking from LRC,, getting stuck at Initializing. When PS starts first, it starts OK and LRC starts OK too and PS can be calle from LRC. This problem appeared after the last update of PS and LR.

          Thanks and regards

          Try the reinstallation as desribed and see if it’s help. A reinstallation can help on several issues.

          Windows 11 64 but, 128 Gb RAM

          When invoking Photoshop 27.9.1 from Lightroom Classic 15.5, Photoshop hangs after “Initializing tools” and never recovers. Have to have Photosop running before invoking it from LR and then things run as they should. This is new - probably came with the latest release as it I used it not long ago calling PS from LR “Open as Layers".

          The workaround is to have PS running before trying to call it from LR but this bug should be fixed.

           

          thanks and regards

          Hi Anshul,

          This happens no matter what method was used to open as layers in Photoshop.

          When Lr stalls, memory usage goes down and CPU fans wind down.

          Drive is SSD, internal.

          Number of photos is inconsistent, sometimes 3, or 4, or 5.

          Here is a dump of lrcc_console.log:

          Thanks for the additional details, ​@Nathan REP. This helps confirm that the behavior appears separate from the other Open as Layers in Photoshop issue you reported, since the stall occurs regardless of whether you invoke the command from the File menu or the right-click menu.

          Before I consolidate this for the product team, could you please help with a few final isolation tests?
           

          1. Test these Edit in Photoshop configurations with the same Nikon Z5 RAW files:

          • TIFF, 8-bit, no compression

          • PSD, 16-bit (Preferences > Edit in Photoshop > File Format > PSD)

          Please let me know approximately how many files you can successfully open as layers with each configuration, or whether they stall in the same way.
           

          2. Please go to Help > System Info > Copy in Lightroom and paste the contents here.
           

          3. Do you currently have more than one Photoshop version installed? For example, Photoshop 27.9.1 together with Photoshop Beta or an older Photoshop release. If so, please list the installed versions.

          Also, there have been instances where installing/uninstalling different Photoshop versions can affect Lightroom-to-Photoshop interoperability, so I’d like to rule that out as well. If we do eventually need to perform a clean reinstall to rule out the application handoff, I would use this order:

          Uninstall Lightroom and Photoshop > restart Windows > install Photoshop first > launch Photoshop once > install Lightroom > launch Lightroom, and test.
           

          4. Please share five Nikon Z5 RAW files that reproduce the stall. You can upload them to Google Drive, Dropbox, WeTransfer, or a similar service and send me the link via DM if the images are private.
           

          I’ve also noted the lrcc_console.log output you provided. I’ll include it with the other information, although I don’t want to assume those particular log entries are responsible until the team reviews them.
           

          If we ultimately need to rule out the application installation/handoff itself, we can then try a clean reinstall in a controlled order. For now, please hold off on reinstalling anything until we have the results above.
           

          Thanks again for the detailed testing. Once I have these remaining results, I’ll consolidate everything and follow up with the Lightroom product team.
           

          Best,
          Anshul Saini
