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

I have the same issue on an M2 Macbook Pro. What's interesting is that if the raw file finally does open it come in with a PSD or TIFF extension instead of the usualy raw extension. I decided to uninstall PS Beta and now when going to PS 2023 from Lightroom with a raw file the image doesn't open at all, so I suspect it might be a Lightroom problem. I can open the raw file with no issue directely from the finder.

Is it just me or does this option not work anymore? When I select it, Photoshop loads but not the image and if I open in the image is doesn't include any Lightroom edits I've made...

Bonjour,

même problème depuis plusieurs jours. Les réactions s'enchainent sur la communauté mais pour l'instant aucune correction ne semble avoir été apportée.

Every since I updated to the newest version of PS I've been getting Error 21: undefined is not an object message when saving and "Edit In PS" from Lightroom is broken. I removed the most recent update and my issues were resolved. 

bonjour je ne peux plus envoyer une photo de lightroom à Photoshop
j'ai ce message de lightroom "le fichier n'a pas été modifieé , car Adobe Photoshop 2024 n'a pas pu être lancé "
j'ai sur mon ordi Photoshop 2023 et la version bêta toutes les deux à jour des mises à jour par adobe creative cloud 

et dans lightroom /préférences/edition externe /version photoshop  j'ai que l'option adobe photoshop 2024

merci pour votre aide 

If you unsinstalled and reinstalled Photoshop and Lightroom Classic recently to fix this post's issue, you may noticed that you ended up with Photoshop 2023 (version 11.7) and Photoshop Beta (version 12.0). If you have none of these running in the background and you selected Edit in Photoshop from your Lightroom image, it will launch it in Photoshop 2023 version 11.7 by default and all works normally.

If you want to use the new Beta version 12.0 to take advantage of new features like Generative Expand, quit Photoshop 2023 and launch Photoshop Beta so it's running in the background. Then go to Lightroom and select Edit in Photoshop. You will get a warning to say it will open it up in Beta. Choose yes to do so. Then you will experience a known Adobe bug, but it still works if you're patient. It may take 2-3 minutes and then you will get a popup in Lightroom that says, "The file could not be edited because Adobe Photoshop (Beta) could not be launched". Don't worry. Just click the blue OK button and wait. You will then see Photoshop Beta open up your Lightroom image. Saving changes in Beta will then save your updates back to Lightroom. This worked for me. Give it a try. 🙂

I've had the same issues with Photoshop Beta.  I ended up removing PS Beta and reïnstalling PS (again), very frustrating as this happened while I was being interviewed for an online photography magazine academy on how I edit my pictures.  Anyway, I redid all the disk access things again (removing PS and LR from the full disk access menu, closing down the menu, restarting the menu and added both again).  It did not work.  I have spent hours again, trying to correct the situation.  Afterwards, I gave up and rebooted my system, which then seemed to work. (I could edit in PS again), but not sure if this was due to other things I was trying to do to get my system running.

Anyway, a workaround I have found that actually works, is putting the raw files on an external SSD (I have a fast Sandisk Extreme Pro, 4Tb).  Going that route works for edit in PS. It's not perfect and for obvious reasons and being more mobile, I want to edit off the internal SSD in my MBP.  But it works for me in a bind and not wanting to spend another couple of hours trying to right a known issue in Adobe/Apple configuration.  Hope this works for you too until they get around to fixing it (if they ever do, as it seems Adobe is not really righting problems raised in the forums)...

Have a great day,

I wonder why i would update to the version (25.0) i've uninstalled because its incapacity to work with lightroom classic... i've uninstalled the 25.0 and use the 24.7  version for making my workflow be a workflow. So i would eventually instal a really working version but surely not the 25.0 until Adobe communicate to a real fix. 

Adobe lightroom classic version 12.4

Adobe Photoshop beta 24.7

Windows 11 version 23h2 ( build 22631.2129)

PS 24.7 hängt sich auf wenn RAW / CR2 oder CR3 Datei mit STRG + E  oder über Menü "Bearbeiten in Photoshop von LRc Vers, 12.4 übertragen wird, Gleiches passiert bei Nutzung Beta Vers. 25.6.  Das ganze begann nachdem die PS Vers 24.7 automatisch installiert wurde (Photoshop 2024 ) Es erschein "Willkommen bei Photoshop, Günther" Fenster mit zuletzt geöffneten Fotos..     Wenn ich "Datei Öffnen" nutze und eine RAW Fotodatei öffne geht Camera RAW  auf, nach "Öffnen" Fenster wegen Dokumenten farbe klicke ich OK dann erscheint Warnfenster "der Vorgang konnte nicht ausgeführt werden weil ein Programmfehler aufgetreten ist, Danach kann ich PS nur noch über Taskmanager schließen.   Windows 10,      PS 24.7 deinstalliert, Beta deinstalliert LRc deinstalliert  Neustart PC, PS 24.6 installiert, LRc installiert. Übergabe von LRc nach PS funktioniert nicht, BETA 25.6 installiert Fehler immernoch.  Hier muss dringend nen BUG-Fix her. Muss 200 Fotos mit PS bearbeiten, Zeitdruck   gerne auch Tel. 0049015158765662. Deutsch und Englisch fehlen mir vermutlich einige Vocabeln bzgl Adobe, Conversation fließend. VG Günther Pfalzgarf

Good evening everyone
I can no longer export the files from Lightroom to Photoshop Beta, I am an error that Photosgop cannot open the file. Until a few days ago everything worked correctly. Do you have solutions?
Thank you
