I have no way to contact Adobe for support
Have you tried- Adobe Photoshop Lightroom Help | Lightroom Classic CC User Guide
Scroll to the bottom of the page and there are links for "Contact Us" and "Adobe Support".
I am also interested to see filenames (for duplicates?). The one highlighted file in your screen clip is a .PSD
You seem to have almost twice as many thumbnail previews (224) in the Catalog as there are photo files on the hard-drive (127). Have you tried to import files twice?
Grey thumbnails sometimes indicate files that the Graphics card cannot display for several reasons, including a problematic monitor profile. https://www.lightroomqueen.com/articles-page/how-do-i-change-my-monitor-profile-to-check-w hether-its-corrupted/
Checking the website of your Graphics card for the latest Drivers can also solve grey previews.
yes I tried that but because they are having higher than normal calls to customer service the only option they gave me was this forum
Funny thing is it was fine one day and then the next day I had this. I have deleted everything and am downl loading Lightroom again to see what happens. everyt was working fine till adobe split Lightroom to make Lightroom cc classic and Lightroom Cc. Since that I have Had problem. I am by no means an expert at Lightroom which is why I love it. Now I’m all confused with the two and can’t even find all my images and lightro Classic is doing this wei missing file grey screen.
and can’t even find all my images
You need to solve this first. You need to know where all your photo files are stored on your hard-drives.
As you are new to Lightroom Classic-CC (v7.0.1) you may not have done a lot of editing with Lightroom, so as well as re-installing the program you might start a new catalog and import your photos once again using the 'ADD' option.
I have deleted everything
A worrying statement that needs more explanation! (deleted what?) I hope you havn't deleted your photo files!
If you have used the 'new' Lightroom-CC (Cloud based), that complicates matters, beyond my limited understanding at the moment.
