Before doing anything, make sure that your Mac is up to date. Here is how:

Turn on your Mac and immediately press and hold the Shift key.
Keep holding the Shift key until you see the login screen, then release the key
Log in (you may need to log in a few times)
Now your Mac is in safe mode. Try opening a file using Preview in safe mode, does it work?
Either case, exit safe mode by restarting your Mac normally (do not press and hold the Shift key)
And test again if the Preview app is working or not.

4. Open Disk Utility (Applications / Utilities) on your Mac. You can also use Spotlight to find and launch the app. Select your disk from the left menu and then click First Aid and then click Run. This will fix volume errors. Please note that this process may take more than one hour.
