Edit in Photoshop images are not appearing

[André 1955]

I work with Lrc V 12.3 and Photoshop V24.4.1 (the latest versions) and Windows 10 -64 bits

This problem comes from the installation of the Photoshop  Beta version! Since I uninstalled it but I have this problem or I can no longer use Photoshop.

My images are not absent from the catalog.

-When I select a photo from Lrc, right click, edit in, Adobe Photoshop = Home page and nothing more!!

-Selection of 2 photos from Lrc, open as layers =  Home page but nothing more I do not see m^me the 2 selected photos !!

-Select a photo from Lrc, open as Smart Object = Photo well opened on the photoshop workspace

You offer me to uninstall Lightroom but I will lose all my library, my predefined settings and all my organization of my  folders??

Can you help me please

When the 'link' between Lightroom Classic and Photoshop has issues, one of the first things to try is this:
1. Use the Adobe Creative Cloud application to uninstall both Photoshop and Lightroom Classic and when asked, keep preferences. 
2. Install Photoshop first, then Lightroom Classic. The order of the product installed is what is very important here.
Better?

"...to uninstall Lightroom but I will lose all my library, my predefined settings and all my organization of my folders??"

No.

Your "library" is your Catalog file. It is not changed or deleted by a re-install of the LrC & Ps apps. And you have made backups of course!

" predefined settings" also are stored in a Preference file (if asked- Do not reset Preferences).

Develop and Local Adjustments also are not affected by a re-install. (Stored in a {Settings} folder.) FILE LOCATIONS 

"organization of my folders"- You folders on a hard-drive are not touched or changed. (As with many other Apps that you might re-install).

The instructions from @TheDigitalDog will fix the problem of Ps not opening.
