When I double click on the preview app, nothing happens. I'm trying to drag files to the preview and the message "The application preview is not open" appears.
I can not remove the shortcut from the dock. I tried to open it in the application folder, and it does not work. I've checked the activity monitor and when I look in the "CPU" tab in "Preview", nothing is displayed. I tried to force me to quit the preview from the Apple menu and right-click on the app.
