Why doesn't mail and icloud settings open on MacbookPRO?

Question

macOS

Greetings.
Please help...
I have a macbookpro with the latest macOS installed. In the evening I closed the laptop, in the morning I opened something and rebooted it. I click on the launch icon of the Mail application - the icon jumps and that's it, nothing happens. Next, I climb into the settings - I press icloud - it says that it can not open the settings window. I'm trying to go to "Internet Accounts" - also, I can not open the settings window.
The rest of the settings open normally (mouse, screen, etc.).
Before this glitch, I did not install anything, I did not do anything like that.
Tell me what could be the matter and how to win?
I thought it might be somehow (as in Windows) to reinstall individual components of the operating system, but I did not find how. )) There is no disk - the system was bought via the Internet (and updated). The computer is not new, it was bought before 2012.
Thank you very much in advance.

Try restoring file permissions in Disk Utility.
