P: Lightroom Classic>Edit in PS: Long Delay+Erroneous Error Message opening Ps Beta 2024 25.0

I had a similar issue just now in MacOS Sonoma 14.1. I had the beta Photoshop installed along with the production release v24. Opening from LrC (latest) opened just fine in the beta Photoshop. I uninstalled the beta because I didn't need it anymore (I only had it installed to try the then-new AI generative fill stuff), then when I tried open-in from LrC, it opened Photoshop 24, but didn't open the file. 

I uninstalled and re-installed Photoshop, and now the edit-in opens the file correctly.

When using Lr 12.5 and attempting to "Photo>Edit In > Open as layers in Ps 25.0" the application just hangs the landing page in Photoshop. I have restarted the Mac runing the new macOS Sonoma 14.0 and it's still not functioning properly. 

Last night I finally found a fix that worked. It involves deleting a file and letting Photoshop create a new one that works. I was cautious and just renamed the old file so it wouldn't be accessed.  Here is a video that explains what to do:

OK, so pressing CTRL-E in Lightroom Classic v12.5 did not launch Photoshop CC v25. Then I read a comment and waited. Lightroom said it couldn't launch Photoshop. I clicked on OK and it did launch Photoshop. I changed the Photoshop workspace from Essentials to Photography. Everything looked like I wanted.

I closed Photoshop. In Lightroom, I pressed CTRL-E again and Photoshop came right up. I had to approve charges first because I was opening Photoshop as Administrator, but then it opened - but on the Essentials workspace, even though Photography was checked. I clicked on Photography and that workspace came up. Is a puzzlement.

Me too! I made a fix to Photoshop CC to prevent a preset error message from appearing when I exited the program. Now Lightroom won't launch Photoshop (I use CTRL-E). Except I read your explanation and I get that too. Lightroom says it won't launch Photoshop but when I press OK, it launches it anyway.

After some years I did a (real) clean reinstallation of MacOS and all programs (without using TimeMachine-Backups) - now both LR and PS are working fine.

I have no longer issues with the print-module nor the "exchange" between LR and PS.

i was using the latest version of both LR and PS and was having the same issue. 

I uninstalled PS and "downgraded" to latest PS Beta version. 

Link between LR and PS is working fine now. Try that.

Same here (Mac) - this is so annoying!

Beside the bug with the print-module (LR keeps crashing everytime) - actually using LR is a horrible experience!

This bugs are known for months and I would declare them not as minor ones. It can't be took so long to fix this...

Good to know it's working for you.
