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.

      Hi Anshul,

      This occurs no matter what method is used to open as layers in Photoshop. It seems independent of the other bug I noted.

      To your other questions:

      The task manager shows memory and CPU going down, not rising; hence, the CPU fans winding down too.

      The drive is SSD, internal.

      The number of photos threshold is inconsistent, sometimes 3, or 4 or 5 raw files.

      Here is a dump of lrcc_console.log:

      Using Lightroom version 9.5, Photoshop version 27.9.1, Windows 11, when trying to open more than a couple RAW files as layers in Photoshop from Lightroom, the “Opening in Photoshop” progress bar on the top left reaches about 10% and then stops. CPU fans initially wind up but stop as well, as though the process stopped. No layers open in Photoshop. Waiting for 10 minutes nothing changes. Stopping the process by clicking on the “x” on the progress bar (top left) and retrying with 2, sometimes 3, or sometimes 4 raw files works, although that seems to relate to the compression set in Preferences; for instance, in “Preferences::Edit in Photoshop” (for SDR) using Zip compression causes the failure when trying to open more then 2 raw files as layers in Photoshop. Using “None” compression can open 3, sometimes 4 raw files as layers in Photoshop. Each RAW file is from a Nikon Z5 with file sizes 27MB to 30 MB each. Clearing cache and restarting Lightroom made no difference. Restarting the computer made no difference. Uninstalling and reinstalling Lightroom made no difference. Turning “Use graphics processor” to off made no difference. Using Lightroom Classic or Bridge I can open numerous raw files as layers in Photoshop with no problem and no limit (10 or more RAW files, no problem).

      Hi ​@Nathan REP,

      Thank you for reaching out again. I noticed you’ve also reported another issue with Open as Layers in Photoshop, but the behavior here appears somewhat different.

      Could you confirm whether this stall occurs regardless of how you invoke Open as Layers in Photoshop:

      • File > Edit in Photoshop > Open as Layers in Photoshop

      • Or by right-clicking the selected images > Edit in Photoshop > Open as Layers in Photoshop?

      Also, does it make any difference whether you’re working from Edit view, Grid/Photos view, or Local?
       

      Some troubleshooting steps to try:

      • Change the "Edit in Photoshop" bit depth to 8-bit temporarily in Preferences > Edit in Photoshop (ProPhoto RGB). With your 27–30 MB Nikon Z5 RAWs, 16-bit + Zip compression creates extremely large intermediate TIFFs. This can overwhelm Lightroom's transfer queue. If 8-bit works with more files, the issue is related to memory/buffer limits in the transfer pipeline for large intermediates.

      • Try PSD format instead of TIFF in Preferences > Edit in Photoshop. PSD uses a different compression path and may not hit the same pipeline bottleneck with multiple files.

       

      A few more questions to dig deeper:

      • When the progress stalls at ~10%, does Lightroom's memory usage (in Task Manager) continue to climb, or does it flatline at that same moment?

      • What drive type is your Lightroom cache/temp location on (SSD vs HDD)? Is it local or external?

      • If you try with exactly 5 files + "None" compression, does it always fail at 5, or is the threshold inconsistent?

      • Share Lightroom's console log after & during the stall. Lightroom Desktop writes a continuous log file at:

        Open File Explorer and navigate to: C:\Users\[YourName]\AppData\Roaming\Adobe\Lightroom CC\lrcc_console.log

       

      Looking forward to your response.

       

      Best,

      Anshul Saini

      I’m not able to duplicate that on my Win 11 system with Nikon raw files. I did notice it takes a while to open when the new features window is showing in PS. 

      What type files are you working on in LrC? Raw, .jpg, .tiff?

      Photoshop 27.9.1


      Just to make sure: Are you 100% sure it’s Photoshop 27.9? Is it possible it’s updated to 27.10? This issue is usually associated with Photoshop 27.10, while downgrading to 27.9 should solve it.
