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

I downgraded, to PS 27.9.1
And disabled Denoise, I just imported a raw NEF file, with no edits, presets,
But the problem still persists, it takes 2-4 minutes, then this error popup shows in LRC
And then eventually opens up in Adobe Photoshop. 
This can really disrupt a decent workflow that you already have.

Open As Layers in Photoshop fails if all the files have AI Denoise applied. (By failed, I mean Photoshop opens but the layers do not load).

Open As Layers in Photoshop causes Photoshop to crash if one of the files has AI Denoise applied but the others do not. (By crash, I mean Photoshop opens an error report log but Photoshop is then inactive and the error report cannot be sent. Force Quit is the only way out of Photoshop).
 

To recreate:

1. Highlight two or more .CR2 RAW files in Lightroom Classic which do not have AI denoise applied.
2. Open as Layers in Photoshop to confirm everything works as expected
3. Apply AI Denoise to one file and then synch the denoise with the other/s. 
4. Highlight all synched files and Open as Layers in Photoshop. Photoshop opens but Layers do not load.
5. Back in LrC, reverse the AI Denoise in the history state (all files) or just turn off Denoise for every file.
6. Highlight all files (which now have no Denoise), Open as Layers in Photoshop for the same images. Everything works as expected.
7. Repeat steps 3 and 4 to toggle the problem back on.

If only one file has Denoise and the others do not then Photoshop crashes as described above. 

LrC 15.5.1, Camera Raw 18.5.1. PS 27.10.0

Apple M4Pro 48GB memory on Tahoe 26.6.2

using Canon 5D MkIV RAW files

This could be related to this problem.

Cannot open multiple Lightroom 15.5.1 images in Photoshop 27.10 as layers.

PS hangs and you can only force quit PS

The problem does not occur in 27.9.1 

Windows 11 / Nvidia Geforce 4060 Ti

Adobe Lightroom 15.5.1 denoise is causing a problem with "open photos as layers in Photoshop" on my apple computer. I have reinstalled both Photoshop and Lightroom to try and solve this issue. 

I can edit an individual photo in Lightroom using denoise and send it to Photoshop with denoise applied by right clicking that individual photo only. But if I try to open multiple photos as layers in Photoshop with denoise applied to any or all of the photos that I am working with, they will not open as layers in Photoshop. The fix is to turn off the denoise on all photos and then they open as layers correctly.

As a real estate photographer, I have been using denoise in Lightroom on all my photos on a daily basis for months, and never had any problems. This problem appeared out of nowhere. Hope this helps. Please reply to kj126150@gmail.com. Thank you

This issue has arisen again with the latest Photoshop update, can anyone suggest what can be done now

Known issue. This thread mentions Denoise as the cause, but of course Denoise uses Raw Details.

After initial edits in LRC I select ‘Raw Details’ but when I try to ‘Open in Photoshop’ it will not open, when I uncheck the raw details box it does open. I have uninstalled and reinstalled both programs but the problem persists.

Photoshop 27.10 has several serious known bugs. One of them:

They are known and the developer team is working to fix these. In the meantime go back to versoin 27.9.1
