External editing in Photoshop no longer working properly

[steve_8334]

Running LrC 13.4 and PS 25.11. Just starting yesterday, I cannot edit my raw file directly in PS from LrC.

• When I select Edit in Photoshop 2024, PS launches, but it doesn't open the raw file.
• As a workaround, I can open the file as a smart object (Edit in/ Open as Smart Object in Photoshop).
• But after editing, I get an error from trying to save the PSD file. The error message is "Error 2: photoshop is undefined. Line:1 ->" (see attached screen grab).
• When I return to LrC, the new PSD file does not appear in the Library unless I synchronize the folder.

I also tried Edit in Photoshop from Lr (not classic). Doesn't work at all: "File could not be opened in Photoshop".

When this issue appeared, I was running LrC 13.2. I tried upgrading to 13.4; didn't solve the issue.

As a workaround, I can open the file as a smart object (Edit in/ Open as Smart Object in Photoshop).

When you are in PS via that method, double check what version PS is (/Help/About Photoshop/)

As I noted in my original post, it's 25.11. It's the only version of PS I have installed at this time.

Hi @steve_8334 ,

At any point of time, had you installed Photoshop Beta?

Nevertheless, please reinstall the Photoshop version 25.11 and check again

[steve_8334]

Yes, I had installed a beta version. I uninstalled it yesterday with no
effect on my issue.

I uninstalled 25.11 and reinstalled it today. Ditto for LrC. So far so good.
