Photoshop not available as default editor in LR Classic

Hi. I use the latest LR Classic och an (updated) Windows 10 Home laptop. For a time I used both PS and PS Beta but when the Gen AI updated PS 2024 arrived I uninstalled the Beta. But then the Default External Editor disappered! See the grayed out area in the enclosed JPEG. (It is in Swedish)
I had to add the PS 2024 as an external editor which means that the PS-related edit functions in LR are grayed out.
Does this mean that I must uninstall/reinstall PS? Or LR? Or both? Or is there a quicker way?
Regards
