DNG doesn't find my photos anymore

[Ian29742469mvl4]

I have recently bought a new computer (Win 11) and am busy installing all my programs. I only run Lightroom 6 but this won't read my Z50 raw .NEF files so I have to use DNG converter. I installed the last version of DNG I was using (14.3?) but when I try to open the location of my photos it says 'No items match your search'. I checked for an update and installed version 15.3, but with the same results. Any ideas what is wrong?

Click on an entire folder. You can't convert individual files; only folders.

I'm clicking on the folder.

Are you selecting the Folder with the Navigation Pane in File Explorer?

OK, it is now sorted, sort of. I managed to convert the files. Lightroom doesn`t like it when I take RAW and JPG together, as I think has been mentioned elsewhere. Neither does it seem to like it when the folder with the converted images was on my desktop -  I had to move it to my 'Pictures' directory, when it was perfectly fine before. Ah well, I can live with that. Thanks for the help..
