opening documents in photoshop from Lightroom not working

[Peter Herreaman]

I have a RAW document in Lightroom with basic adjustments, when I use edit in Photoshop 2022 all the items in the dropdown list are unavailable. It was working yesterday, I must have done something but not knowing what?

I am presuming you are using Lightroom-CLASSIC.

Grey 'Edit-In' menus for Photoshop and External Editors may be caused by-

1) The photo is 'missing'. Lightroom does not know where the original photo is stored-

It has been deleted, renamed, moved, by the OS (File Browser / Finder) outside of LrC.  Grid view thumbnail is showing a [!] on the border? (or possibly a corrupt file).

Or Folders are showing a [?] in the Folder panel.

Or the Drive does not show a Green light on the Drive name header above the folder panel.

2) You are using Smart Previews and the original file is not connected to the computer or available to Lightroom. (eg. external usb drive not connected). Plug in the external drive- check that it is using the same Name/Letter as before. (Also see the link for Missing photos)

3) Lightroom and Photoshop are not linked correctly in Registry/plist.  See this link-
