unable to save my files

Yesterday I updated photoshop and today I can't save my files, not with ctrl. + s, not with save as, not as PSD, TIFF, not to the cloud, I always just get a message of a program error. After it happened with 4 open files, I lost all of my work, restarted the computer, restarted my work, could save two times, but at the 3. saving again that error message. "no se ha podido guardar como "_MG_...pds" porque ha habido un error de programa.
