Preview app error -10810

Question

Just started to get this error when launching Preview or opening files that use Preview automatically such as PDFs. How can I fix it, please?

Answer 1

Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
If you can't launch the application, log out and log back in, or reboot, and try again.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the Process Name column in the process table to sort the entries by name. Make sure there's a column with the heading User. If there isn't, select
View ▹ Columns ▹ User
from the menu bar.
Hide the Activity Monitor window (don't close it), go about your tasks as usual, and wait for the problem to come back. When it does, check the process list for two things:
Multiple processes with the same name and the same user
Processes shown in red with the words "Not responding" next to the name
If you see such an entry in the list, double-click it. A small inspection window should open. At the top of that window is a field labeled Parent Process. Make a note of the name of the parent process.
Quit Activity Monitor, and if necessary, log out or reboot again. Post the names of the processes that met the above criteria, and the names of their parent processes.
