Wonder if anyone else is having this problem. When I use The newer Lightroom on mac I can edit image fine. But whe I try to send it to Photoshop, it won't send. Also if I have to quit Lightroom I have to forsequit. I can work in Lightroom classic just fine.
Sorry that you cannot send images from Lightroom desktop to Photoshop.
Which version of Photoshop and Lightroom are you using and what is your opearating system?
Would you mind resetting the Lightroom app preferences to default? Press and hold the Shift + Option + Delete keys.(Mac) or Press and hold the Shift + Alt keys while starting Lightroom. A dialog box should appear asking you restore the preferences.
