The problem was because somethign went wrong with the redirectors, I moved the Textures folder and Material folder at the same time, and when fixing the redirectors en folder, something screwed.
I had luck that I made a backup of the project 2 days ago, im using that backup
I did the same with my backup copy and got damaged the same way, so to prevent this. I move first my TEXTURE FOLDER, clean all redirectors. (Saved the project) and the move the MATERIAL FOLDER, and clean redirectors and didnt broke.
google bring me here and it work!!!. My case is in unreal 4.27, materials lost connect with all materials. asset Action>migrate show the path of the textures, rename your folders structure same with the show and all material working again!.
