Hello.
Try resetting your sims 4 folder and see if that helps. To do that, move your sims 4 folder to the desktop. Then start the game, and a new sims 4 folder will be generated. Start a new game and test to see if the issues have been fixed. If it is working okay, exit the game and then add back the "options.ini" file and the "saves" , "screenshots" "tray" "custom music " and "mods" folders to the new sims 4 folder, replacing the new generated file/ folders with the old file/folders, testing after replacing each one to make sure the game is working okay.
