'?' icon on my dock

I'm afraid I can't really do that because my friends is a teacher and the computer was given to her by the uni so I don't have admin power so I can't restart on safe mode I don't have the password, and yes I did try to restart it and it doesn't worked like I said in the question.

Take it to the uni IT and have them fix it.

I saw a problem with the Dock all of the first party app like Calendar,

Notes Message etc icons were replaced with the '?' icon and the Dock seem to be none responsive

Did you try Shutting down and restarting the Mac...

if your hands are tied—you can always drag the ? marks off the Dock one by one and from Applications folder drag and drop the icon you want to see.

or use the Option>Remove from Dock

Try restarting the Dock by going to the Terminal and running this command:

killall Dock

followed by the Return key.

It will take about 2 seconds for the Dock to restart.
