Your question does not translate to English very well. The Nikon D850 requires at least Camera Raw 9.12.1, Which is not compatible with Photoshop CS6. It will be necessary for you to use the DNG converter. You should use at least DNG converter 9.12.1, Although you could use the latest version as well.
When you are choosing what to convert using the DNG converter, just select the folder but do not open the folder. If you open the folder in the DNG converter then you will be informed that there are no raw files to convert. Only choose the folder. I don't know if this will help you.
I don't have the latest DNG converter installed because I don't use it very often. I have DNG converter 10.3. I also don't have the Nikon D850, so I downloaded a sample NEF file. All I can say is that I opened the DNG converter and selected that NEF file, and it converted it to a DNG file without any problems. I'm sure if I downloaded and installed the latest converter the results would be the same. Here is a screenshot from Bridge of the NEF file and the converted DNG file.
I discovered one thing different with DNG converter version 11. It did not find the NEF file if it was simply on my desktop. It was necessary for me to create a folder on the desktop and place the NEF file in that folder. Then, in the DNG converter, it was necessary to choose that folder. When I did that the conversion worked as expected. With the earlier version of the Converter, I was able to just do the conversion on the desktop.
