We're sorry about the trouble with Photoshop. Would you mind sharing the version of Photoshop you're using along with your computers operating system? Since when are you facing this issues? How & in which format are you facing the file?
You can try disabling the option to Use Graphics Prcoessor from Photoshop by going to the Preferences, then Performance. Once done, relaunch Photoshop & try to save another file to check if it helps.
