To uninstall a game on your PS4, follow the steps found here. This issue just cropped up recently during my second playthrough, and previously I hadn't been having issues with saves unlike so many other people.

Then save the settings and check if the Fallout 4 stuttering or lagging issue has been solved. According to users, you may be able to fix this issue simply by changing the resolution of the game. Each character/game has fucked up after the first 24 save hours. Now, run the game and see if Fallout New Vegas crashing issue appears again or not.
