P: LrC 14.5 Edit in Photoshop does not work when opening RAW photos

I am trying to complete a focus stack for a macro, shooting in RAW with a Nikon D850..  I import the files into Lightroom Classic, where they show as NEF files, then select which of the photos i want to include in the stack. I then right-click the photos, select "Edit in" and select "Open as layers in Photoshop."  Photoshop opens, but I get a blank window - no photos.  When I try the same process using JPEG files, the photos all appear.  I have the same problem when I try to open a single NEF photo through "Edit in" & "Edit in Photoshop 2025."  If I open the NEF files directly from my hard drive through Ps, they load, and I can complete the focus stack, save the result back to the hard drive, then import it into LrC.  But that is a pain, and since I pay for the product, I don't think it's unreasonable to expect it to work properly!!!  How can I get the NEF files to open in Photoshop through the "Edit in" option?  I have the Creative Cloud subscription, so Photoshop (v. 26.10.0), Camera RAW (v. 17.5), and Lightroom Classic (v. 14.5) are all current.  My PC OS is Windows 11.  I have confirmed that my External Editing default is Photoshop 2025.

I updated to Photoshop 26.10.0 and now "Open in Adobe Photoshop 2025" doesn't work.  Photoshop opens to a home screen, but never opens the image.  "Open as a Smart Object in Photoshop" does the same thing.

I am running Windows 11 Professional.

I tried uninstalling and reinstalling both apps per a post from several years ago but it didn't help.

I updated Lightroom Classic and Photoshop 2025 today. I select the photo I have adjusted in Lightroom go to Photo>Edit in Photoshop 25> Edit with Lightroom Adjustments, Photoshop opens but the selected photo does not appear. Any ideas anyone? Windows 11 latest verions of Photoshop and Lightroom Classic.

For all those posting here, the apostrophe (') in file pathnames problem is a bug in LrC 14.5.

Although removing them by renaming solves the problem when that is the issue, I am getting the impression that there is another problem for Mac users only preventing photos being opened from LrC into Photoshop using Edit In. For those reports, the apostrophe doesn't seem to be the cause. 

The apostrophe issue needs to be fixed since it is not an 'illegal' character in folder/filenames and shouldn't be causing this problem.

As for Mac users who don't have an apostrophe in the folder pathname, but still can't open photos from LrC into Ps, that is something that needs to be investigated by Adobe. I don't have a Mac to test on.

I am making edits in LR Classic, then trying to open the photo to edit in PS by right-clicking, and clicking "Edit in PS 2025." Each time, the program opens up, but not the photo. This has been working flawlessly forever, but stopped working this morning. I recently updated to v26.10, and thought it might be a problem with the new version, but when I downgraded to 2569 I'm having the same problem. No error messages, and no open dialogue boxes come up, just doesn't want to open the image.

Same here. I hope this bug gets fixed soon.

I'm having the same problem on a Windows machine.

I had this issue recently and it turned out to be because the file had an apostrophe in the name. So maybe now some characters are blocking the transfer. Oddly, the file would open in PS directly. But trying to transfer from LR to PS only worked when I renamed it

Since upgrading Lightroom Classic, I am no longer able to send photos from there into Photoshop 2025. Is anyone else having the same issue? If so, do you have a fix or a work around?

I am using Lightroom Classic v14.5 to try and "edit in" Photoshop v26.10.  This worked yesterday morning prior to installing the new version of Photoshop.  Photoshop will open, but the image does not open to edit or open as a smart object.  I am running the latest Mac OS.  I also have uninstalled Lightroom and Photoshop and then reinstalled them with Photoshop first.  I have allowed Full Disk Access to Lightroom and Photoshop.
