Copy/paste not working: pboard crash

After upgrading to build 17B1003 (Security Update 2017-001) copy/paste stopped working. There's a noticeable freeze when trying to copy anything to the clipboard.


Investigating the logs revealed that it is due to pboard crash with the following message:


Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** initialization method - initWithFormat:locale:arguments: cannot be sent to an abstract object of class NSString : Create a concrete instance!'


It is always accompanied with another Sandbox message:


Sandbox: pboard(664) deny file-read-data /usr/libexec


The error is reproducible in Safe mode and under any user.


How to fix this?

MacBook Air (13-inch, Early 2015), macOS High Sierra (10.13.1)

I've recently had a call from Apple Support, and it was super helpful.


The issue was fixed after opening the Terminal.app, typing


sudo update_dyld_shared_cache-force


It will ask for a password. Provide the password, wait for the command to finish, and then restart.
