My preview app is defect. How can i replace it? (Osx v 10.12.6)

Trouble started editing screenshot (jpg) where i was puting in comments in form of rectangular boxes and text annotations.

Suddenly a yellow crosshair occured on text field i as editing a textbox, and the whole machine froze.

After a hard reboot I no longer have a working preview app.

It consistently bombs out giving me access to the full stack-trace and reporting to apple.

Anyone knows if there is data that causes this (defect fonts, caches etc) or if there is a way to replace the Preview.app from backup (I have timemachine).

On a first attempt of this I was not allowed to eplace it "since it is required".

MacBook Pro with Retina display, macOS Sierra (10.12.6)

You would have to boot into the Recovery Partition and reinstall the OS to replace it.

OS X Recovery

OS X Recovery (2)

Might be a corrupt .plist.

Do a backup, preferably 2 backups on 2 separate drives.

Quit the application.

Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library. Then go to Preferences/com.apple.Preview.plist and com.apple.Preview.LSSharedFileList.plist. Move the .plists to your desktop.

Restart the computer, open the application, and test. If it works okay, delete the plists from the desktop.

If the application is the same, return the .plists to where you got it from, overwriting the newer one.

Thanks to leonie for some information contained in this.
