'Edit In' command in Lightroom greyed out

Hi, I've recently done system recovery on my laptop and re-installed newest versions of Lightroom Classic (9.0) and Photoshop (21.0.1). I can no longer send files from Lighroom to Photoshop as all the items in 'Edit In' sub-menu are greyed out. I've tried changing preferences for 'external editor' back and forth few times and installing older versions of Photoshop (back to 19) but nothing changes. What can be done to fix this issue?
